Answer:

The answer to your question is:

a)   f(a + 2) = 2a + 6

b)  g (a + 2) = a² + 5a + 8

Step-by-step explanation:

e) f(a + 2) = 2(a + 2) +2

  f(a + 2) = 2a + 6

f) g ( a + 2) = (a + 2) ² + (a + 2)

  g (a + 2) = a² + 4a + 4 + a + 2 + 2

  g (a + 2) = a² + 5a + 8

Answer:

e. 2a+6

Step-by-step explanation:

e. substitute in a +2

f(a+2)=2(a+2)+2

simplify

f(a+2)=2a+4+2

f(a+2)=2a+6

f. substitute in a+2

[tex]g(a+2)=(a+2)^{2} +(a+2)+2[/tex]

simplify

[tex]g(a+2)=a^{2} +2^{2} +a+2+2[/tex]

[tex]g(a+2)=a^{2} +4+a+4[/tex]

[tex]g(a+2)=a^{2} +a+12[/tex]
