If f(x) = 4x + 3 and g(x) = 3x, evaluate for x = -1/2

Step-by-step explanation:

Given the function and the function , to evaluate for , you need to substitute it into each function.

Then, for the function f(x), when  , you get:

For the function g(x), when  , you get:

f(-1/2) = 1

g(-1/2) =-3/2

Step-by-step explanation:

f(x) = 4x+3

Let x = -1/2

f(-1/2) = 4(-1/2) +3

f(-1/2) = -2 +3

f(-1/2) =1

g(-1/2) = 3(-1/2)

          = -3/2
