Explanation:

Step1: Substitute x = 5

$f(5)=5 + 3$

Step2: Calculate the result

$f(5)=8$

Step3: Substitute x = 0

$f(0)=0 + 3$

Step4: Calculate the result

$f(0)=3$

Step5: Substitute x=-1

$f(-1)=-1 + 3$

Step6: Calculate the result

$f(-1)=2$

Step7: Substitute x = 2a

$f(2a)=2a + 3$

Step8: Substitute x=a + 2

$f(a + 2)=(a + 2)+3$

Step9: Simplify the expression

$f(a + 2)=a+5$

Answer:

a) 8
b) 3
c) 2
d) $2a + 3$
e) $a + 5$
