Let f (x) = - 2x - 7 and g (x) = - 4x + 6. Find (f o g) (-5)

A. - 6

B. 3

C. 26

D. - 59

(f o g) (x) means f (g (x))

one way to find (f o g) (-5) is to find the value of g (-5) then subsitute that for x in f (x)

so

g (5) = - 4 (-5) + 6

g (5) = 20+6

g (5) = 26

f (g (5)) = f (26) = - 2 (26) - 7

f (g (5)) = - 52-7

f (g (5)) = - 59

answer is D

The answer is - 6. so the (f o g) is - 6
