Question

Evaluate the function. h(t)=-2t+2; Find h(-3t)

Answer 1

You just replace t to -3t

So h(-3t) would be -2(-3t)+2 = 6t+2

If you just meant h(-3) then that would be 6+2 = 8 via same steps.

Answer 2

What you want to do is plug in -3t for the value of t which will give you
$h( - 3t) = - 2( - 3t) + 2$
After doing all the necessary operations, you will end up with
$6t + 2$
which is your answer
