Question

Consider the functions f(x) = 3x2 + 1 and g(x) = x + 3. What is the value of f[g(−1)]?

7

37

13

12

Answer 1

what is f(x) eq?

Answer 2

f(g(-1)= f(-1+3)=f(2)=3(2)^2+1=3(4)+1=12+1=13

Answer 3

C???

Answer 4

it says to take g function and evaluate at -1 so -1+3=2 so then take f function and evaluate at 2 so \[3(2)^{2}+1\]

Answer 5

does that help?

Answer 6

ya i guess

Answer 7

yes or no not ya?

Answer 8

yes

Answer 9

good job
