Question

Given the following: f(x)=x^2-8 x+4 ; g(x)=4 x+3; and h(x)=x+2.

What is the result of the following:

A. 4x^2 - 3x + 8
B. 4x^2 + 5x - 6
C. 4x^2 + 11x + 6
D. 4x^2 + 11x - 6

Answer 1

To find the result of the expression A. 4x^2 - 3x + 8, substitute the values of x^2, x, and constant terms from the given functions f(x), g(x), and h(x) respectively.

Step-by-step explanation:

To find the result of the expression A. 4x^2 - 3x + 8, we need to substitute the values of x^2, x, and constant terms from the given functions f(x), g(x), and h(x) respectively.

Substituting the values, we get:

4x^2 - 3x + 8 = (4)(x^2 - 8x + 4) - 3(4x + 3) + 8 = 4x^2 - 32x + 16 - 12x - 9 + 8 = 4x^2 - 44x + 15.

Therefore, the result of the expression A. 4x^2 - 3x + 8 is 4x^2 - 44x + 15.
