Please help ASAP 40 points!!

If f(x) = -5^x - 4 and g(x) = -3x - 2, find (f-g) (x).

A. (f-g)(x) = -5^x - 3x - 6
B. (f-g)(x) = -5^x + 3x - 2
C. (f-g)(x) = -2x-2
D. (f-g)(x) = 5^x - 3x + 2

Answer 1

b) -5^x + 3x - 2

Explanation:

(f-g) = -5^x - 4 - (-3x - 2) = -5^x - 4 + 3x + 2 = -5^x +3x - 2

therefore, the answer is b) -5^x + 3x - 2

hope this helps! <3
