Question

If f(x)=3^x+10x and g(x)=2x-4, find (f-g)(x)

A 15x-4
B 3^x-8x+4
C. 3^x+8x+4
D 3^x+12x-4

Answer 1

C. 3^x+8x+4

Explanation:

i did it

Answer 2

C

Explanation:

The equation (f-g)(x) is f(x) - g(x) by subtracting the equations.

`(f-g)(x) = 3^x + 10x -(2x-4)\\(f-g)(x) = 3^x + 10x -2x + 4\\(f-g)(x) = 3^x + 8x + 4`
