F(x) = x + 8 and g(x) = -4x - 3, find (f-g)(x)

5x + 11

Step-by-step explanation:

We are subtracting function g(x) from function f(x).

Write f(x) as is:  f(x) = x + 8.

Then change all of the signs of g(x):  -g(x) = 4x + 3.

Now combine like terms for the sum (f - g)(x) = x + 8 + 4x + 3.  We get

(f - g)(x) = 5x + 11

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the correct answer is 1.7
