*f*(*x*) looks linear. *g*(*x*) looks quadratic. *h*(*x*) looks trigonometric.

Find a transformation that works for each of them.

These composite functions can be evaluated with the table.You do not need to use the equations from part (a).

*h*(*π*) = −(2)*g*(−2) = 0*f*(0) = −5

so *f*(*g*(*h*(*π*))) = −5

*g*^{ −1}(4)

Translation: On the *g*(*x*) table, what *x*-value has a *y*-value of 4? Use the table... do NOT find the inverse function... that would be a waste of time!

Refer to hint in part (ii).

*f*^{ −1}(*h*(*π*)) = 1
