Question

Given that f(x) = x2 − 4x − 3 and g(x) = the quantity of x plus three, over four , solve for f(g(x)) when x = 9.

Answer 1

a. −6

Explanation:

Answer 2

If x = 9 then it would go f(x) = (9)2 - 4(9) - 3 = 15
f(x) = 15 x = 9 g(x) = 3 [x + 3 / 4, 12/4, 3]
If x is 9 and f(x) is 15, f alone would be 6, f(g(x)) = 9
