Question

Given functions f(x) = x 2 -1 and function g (x) = 3x for which value of x does f (x) = g(x)

Answer 1

Explanation:

Set up the composite result function. f (g(x)) f ( g ( x)) Evaluate f (x2 −x) f ( x 2 - x) by substituting in the value of g g into f f. f (x2 −x) = 2(x2 − x)+1 f ( x 2 - x)
