3 answers 218 people helped given function is f (x)=x2−9x−3 since the denominator can not be zero x−3≠0⇒x≠3 the domain of the function is R− {3} y=f (x)=x2−9x−3y= (x−3) (x3)x−3y=x3 for x∈R− {3}y≠33 f (x) is not defined for x=3y≠6 range of the function is R− {6} hope this helps youThe 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 value Therefore, the range of f(x) is the union of the range of the two pieces, namely y > 1 (When x = 15, y = 1, so y = 1 is clearly in the range of f(x)) I ended up making a table of values in a spreadsheet to determine the range It seems that the fact that the function is fractional with an absolute value is throwing us off
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) Mathematics High School verified answered • expert verified For the function f (x) = 3 (x − 1)2 2, identify the vertex, domain, and range The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2 The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2Find the domain and range of the following functions 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
