Answer:

Explanation:

We have

f(x) = 6x + 5

g(x) = 3x

To find the value of either of these functions for a specific value of x, simply substitute that value into the corresponding function equation.

$\bold{f(2)}$
Substitute x with 2 in 6x + 5
==>
$6\cdot \:2+5=17$ (Answer)

$\bold{g(4)}$
Substitute x with 4 in g(x) = 3x
==>
$3 \cdot4=12$ (Answer)

$\bold{f(-2)}$
Substitute x with -2 in 6x + 5

$6\left(-2\right)+5=-7$ (Answer)

$\bold{g(0)}$
Substitute x with 0 in g(x) = 3x
==>
$3\cdot0=0$ (Answer)

$\bold{f((1)/(2))}$
Substitute x with
(1)/(2) in 6x + 5
==>
$6\cdot (1)/(2)+5 = 3 + 5 = 8$ (Answer)

$\bold{g(-4)}$
Substitute x with -4 in g(x) = 3x
==>
$3\left(-4\right) = -12$ (Answer)
