Question

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

A. 3x + 6x + 2
O B, 3* - 6x + 2
O c. 17x - 2
O D. 3* + 14x - 2

Answer 1

A. 3^x + 6x + 2.

Explanation:

(f - g)(x) = f(x) - g(x)

= 3^x + 10x - (4x - 2)

= 3^x + 10x - 4x + 2

= 3^x + 6x + 2.

Answer 2

The answer is A

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

= 3^x+10x-4x +2

= 3^x +6x+2
