Answer:

A. 7

B. -3

C. 8

D. 13

E. 5a+17

F. $a^{2}$ + 8a + 20

Step-by-step explanation:

A. f(1) = 5*1 +2, which equals 7

B. f(-1)= 5(-1)+2 which equals -3

C. g(-3)= (-3)^2+ 2(-3)+ 5 = 9- 6+ 5 = 8.

D. g(2)= (2)^2+ 2(2)+ 5= 4+ 4+ 5= 13.

E. f(a+3)= 5(a+3)+2 = 5a+ 15+ 2= 5a+ 17.

F. g(a+3)= (a+3)^2+ 2(a+3)+ 5= $a^{2}$ + 6a+ 9+ 2a+ 6+ 5= $a^{2}$ + 8a+ 20.

<h2>Explanation:</h2>

Remember you have to provide complete questions in order to get exact answers. Here I'll provide a general explanation, so:

<h3>First.</h3>

$f(x)=14x+3$

The slope is:

$m=14$

The y-intercept is:

$b=3$

By using graphing tool, we get the first graph shown below.

<h3>Second.</h3>

$f(x)=-4x-3$

The slope is:

$m=-4$

The y-intercept is:

$b=-3$

By using graphing tool, we get the second graph shown below.

<h3>Third.</h3>

$f(x)=-14x-3$

The slope is:

$m=-14$

The y-intercept is:

$b=-3$

By using graphing tool, we get the third graph shown below.

<h3>Fourth.</h3>

$f(x)=14x-3$

The slope is:

$m=14$

The y-intercept is:

$b=-3$

By using graphing tool, we get the fourth graph shown below.
