Question

Let f(x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
Select the correct response:
f(x) – g(x) = 7x + 1
f(x) – g(x) = 3x – 5
f(x) – g(x) = 7x – 1
f(x) – g(x) = -3x + 5

Answer 1

Answer:

f(x) - g(x) = 3x - 5

Step-by-step explanation:

Hi,

To subtract f(x) and g(x), we need to do (5x - 2) - (2x + 3). We solve and we get 3x - 5. So, f(x) - g(x) = 3x - 5.

The second answer choice is correct.

I hope this helps :)

Answer 2

B
5x-2 - (2x+3)
distribute negative
5x-2- 2x-3
combine like terms
answer is B. 3x-5
