Question

evaluate the function when x=4 g(x)=-2x-3 and h(x)=7x+15

Answer 1

Answer:

• $g(4) = -11$

• $h(4) = 43$

Step-by-step explanation:

Given the functions

$g(x)=-2x-3$

$h(x)=7x+15$

• Evaluating $g(x)=-2x-3$ at x=4

putting x = 4

$g(x)=-2x-3$

$g(4) = -2(4)-3$

$g(4) = -8-3$

$g(4) = -11$

Therefore,

at x = 4, g(4) = -11

• Evaluating $h(x) = 7x + 15$ at x = 4

Putting x = 4

$h(x) = 7x + 15$

$h(4) = 7(4) + 15$

$h(4) = 28+15$

$h(4) = 43$

Therefore,

at x = 4, h(4) = 43
