The functions $f$ and $g$ are defined in this table.

Evaluate the following based on the table. If it is not possible to determine the answer, type in $"$np$"$ for not possible.

a$.f(2)=$

Correct! The input is $2.$ The input $2$ is mapped by $f$ to the output $-8,$ so $f(2)=-8.$

b$.$ Solve $g(x)=-5.x=$

syntax error

c$.f(g(2))=$

syntax error

Try again. What is the input of the function $g?$ What is the input of $f?$

d$.g(g(1))=$

e$.g(f(-2))=$

syntax error

f$.g(f(1))=$

syntax error

g$.$ Solve $f(g(x))=6.x=$
