Let f (x) = - 3x + 2 and g (x) - 4x + 6. Find (f•g) (-5).

(f•g) (-5) = - 238

Step-by-step explanation:

We have that:

f (x) = - 3x + 2

g (x) = 4x + 6

Find (f•g) (-5).

First we find (f. g) (x)

So

f (x) * g (x) = (-3x + 2) * (4x + 6) = - 12x² - 10x + 12

When x = - 5

-12 (-5) ² - 10 (-5) + 12 = - 238

(f•g) (-5) = - 238
