Find the domain and range of the real function f(x) = x/1+x^2
Find the domain and range of the real function f(x) = x/1+x^2- f = { ("x , " 𝑥2/(1𝑥2)) x ∈ R } We find different values of 𝑥2/(1 𝑥2) for different values of x Domain Value will always be between 0 & 1 We note that Value of range y = 𝑥2/(1 𝑥2) is always positive Also, it is always between 0 and 1 Hence, Range is any positive integer between 0 and 1 with 0 included Thus, Range of f = 0, 1) Find the domain of each of the following functions given by f(x) = (x^3 x 3)/(x^2 1) asked in Sets, Relations and Functions by RamanKumar ( 499k points) sets
The domain is x in (oo,1) uu(1,oo) The range is y in (oo, 2sqrt8 uu 2sqrt8, oo) As we cannot divide by 0, x!=1 The domain is x in (oo,1) uu(1,oo) Let y=(x^21)/(x1) So, y(x1)=x^21 x^2yx1y=0 In order for this equation to have solutions, the discriminant is Delta=0 y=(4(164*(4)))/(2) y=(4sqrt32)/2=(2sqrt8) y_1=2sqrt8 y_2=2sqrt8 Therefore the range is y in (oo, 2sqrt8 uu 2sqrt8, oo) graph{(x^21)/(x1 The domain of f (x) is Df(x) = R −{ − 1,1} To calculate the range, we need to calculate f −1(x) Let y = x2 1 − x2 We interchange y and x x = y2 1 −y2 Now, we calculate y in terms of x x(1 −y2) = y2 x − xy2 = y2 y2(x 1) = x Find the domain and range of a function f(x)=1/(1x^2) Forums Maths, Math, Homework, Do My Homework Email this Topic • Print this Page Swapnil Reply Mon 23 Jun, 14 1144 am Find the domain and range of a function f(x)=1/(1x^2) Stumble It!

Find the domain of the function \(f(x)=x^2−1\) Solution The input value, shown by the variable \(x\) in the equation, is squared and then the result is decreased by one Any real number may be squared and then be decreased by one, so there are no restrictions on the domain of this function The domain is the set of real numbers 1 Confirm that you have a quadratic function A quadratic function has the form ax 2 bx c f (x) = 2x 2 3x 4 The shape of a quadratic function on a graph is parabola pointing up or down There are different methods to calculating the range of a function depending on the type you are working with05, x is greater or equal to 5

The function f(x) = x 2 has a domain of all real numbers (x can be anything) and a range that is greater than or equal to zero Two ways in which the domain and range of a function can be written are interval notation and set notationThere are no restrictions on domain The domain is (,) Since the value of x is squared, f(x) will always be equal or greater than 0 Domain {xl x≠0} Range 1,1 or just 1 and 1, In f(x), all y values are either 1 or 1 The range contains no verticle y values greater than or less than 1 and 1 So maybe I should write this range as {yl y = 1 and 1} or 1U1?

F(x) = 1 x 2 Solution For any values values of x, the function will give defined values It will never become undefined So, domain is all real values that is R The range of x 2 lies between 0 to ∞ But we need find the range of 1 x 2 0 ≤ x 2 ≤ ∞ Multiplying by negative through out the inequality, we get ∞ ≤ x 2 ≤ 0 Add 1, through out the inequality, we get 1 ∞ ≤ x 2 ≤ 1 0 ∞ ≤ x 2 ≤ 1 Click here 👆 to get an answer to your question ️ The domain of the function is given Find the range f(x) = 2x 1 Domain {2, 0, 2, 4} Misc 5 Find the domain and the range of the real function f defined by f (x) = x – 1 Here we are given a real function Hence, both domain and range should be real numbers Here, x can be any real number Here, f (x) will always be positive or zero Here value of domain (x) can be any real number Hence, Domain = R (All real numbers) We note that that range f (x) is 0 or positive numbers, So range cannot be negative Hence, Range
So, the domain of the function f(x) is (∞,∞) Now to find the range, say f(x)= y, which gives x²9=y² or, x= ±√(y²9) Since x is a real number, y²9 must be positive or, y²>9 which gives y ∈ (3,∞),since y>0, which is the required range of f(x)Y = f (x) = (1 − x 2) 1 For range, y = (1 − x 2) 1 ⇒ y − y x 2 = 1 ⇒ y x 2 = y − 1 ⇒ x 2 = y y − 1 ⇒ x = ± y y − 1 ∴ y = 0 The term under the root has to be positive casei caseiiFor the reciprocal squared function latexf\left(x\right)=\frac{1}{{x}^{2}}/latex, we cannot divide by latex0/latex, so we must exclude latex0/latex from the domain There is also no latexx/latex that can give an output of 0, so 0 is excluded from the range as well Note that the output of this function is always positive due to the square in the denominator, so the range
Answer The domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4 You can check that the vertex is indeed at (1, 4) Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y valueFirst week only $499!F (x)=1/x2 Found 2 solutions by jim_thompson5910, MathLover1 Answer by jim_thompson5910 () ( Show Source ) You can put this solution on YOUR website!
