Question

Can I get a little help I’m lost

Answer 1

e. 2a+6

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

`g(a+2)=(a+2)^(2) +(a+2)+2`

simplify

`g(a+2)=a^(2) +2^(2) +a+2+2`

`g(a+2)=a^(2) +4+a+4`

`g(a+2)=a^(2) +a+12`

Answer 2

The answer to your question is:

a) f(a + 2) = 2a + 6

b) g (a + 2) = a² + 5a + 8

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
