Answer:
the answer for w = -4 is -32
Explanation:
this is a question on functions.
we take each value of w and substitute it into the function (the expression on the right). the first one is done, as you can see.
first we take -4, and everywhere we see w in the function, we replace it with -4.
- 5(-4) + 12
-4 cubed is -64 (because -4 squared is 16, so multiply that by -4 again to get -4 cubed)
-5 times -4 is positive 20
and we already have the 12
so we have: -64 + 20 + 12
which is -44 + 12
which equals -32
simply repeat this process with all the other values of w
ask me again if you're stuck
good luck!
