Explanation:

Step1: Substitute $a=-2$ into $f(a)$

$f(-2)=4(-2)-8$

Step2: Calculate the value

$f(-2)=-8-8=-16$

Step3: Substitute $b=1$ into $g(b)$

$g(1)=-2(1)^2+1-7$

Step4: Calculate the value

$g(1)=-2+1-7=-8$

Step5: Substitute $c=-5$ into $h(c)$

$h(-5)=\frac{3}{5}(-5-15)$

Step6: Calculate the value

$h(-5)=\frac{3}{5}(-20)=-12$

Step7: Substitute $d=4$ into $p(d)$

$p(4)=7$

Answer:

a. $-16$
b. $-8$
c. $-12$
d. $7$
