Question

The last one for tonight


Consider the functions f(x) = 3x2 and g(x) = 2(x + 9). Find f[g(-7)]. Please show all of your work for full credit.

Answer 1

help!!! T_T

Answer 2

plug -7 for the function of g(x)
then the answer for that function goes into f(x)

g(-7)=2(-7+9)

f(g(x)) = 3( 2(-7+9))\[^{2}\]

Answer 3

f(g(x)) = 3( 2(-7+9))^2

Answer 4

is that all? :c

Answer 5

yes just work out the equation 3( 2(-7+9))^2
add -7 and 9
then multiply the answer by 2
then square it
then multiply it by 3
and thats the final answer

Answer 6

thanks! C:
