Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fxg)(-5).<br><br> a. -59<br> b. 3<br> c. 26<br> d. -6
DedPeter [7]

Answer:

78

Step-by-step explanation:

The given functions are:

f(x) =  - 2x - 7

and

g(x) =  - 4x + 6

(f \times g)(x) = f(x) \times g(x)

(f \times g)(x) = ( - 2x - 7)( - 4x + 6)

When we plug in x=-5, we get:

(f \times g)( - 5) = ( - 4 \times -  5 + 6)( - 2 \times  - 5 - 7)

(f \times g)( - 5) = ( 20 + 6)( 10 - 7)

(f \times g)(5) = ( 26)( 3) =7 8
