Question

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

Answer 1

f(-1/2) = 1

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

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

Answer 2

`f(-(1)/(2)) = 1`

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

Explanation:

Given the function
`f(x) = 4x + 3` and the function
`g(x) = 3x`, to evaluate for
`x=-(1)/(2)`, you need to substitute it into each function.

Then, for the function f(x), when
`x=-(1)/(2)`, you get:

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

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

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

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

`f(-(1)/(2)) = 1`

For the function g(x), when
`x=-(1)/(2)`, you get:

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

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