Answer:

(f ○ g)(- 1) = 11

Explanation:

to evaluate ( f ○ g)(- 1) find g(- 1) then substitute the value obtained into f(x)

g(- 1) means what is the value of g(x) when x = - 1

from the table when x = - 1 , g(x) = - 3

now evaluate f(- 3) , which means what is the value of f(x) when x = - 3

from the table when x = - 3 , f(x) = 11
