Answer:
-4 : -32
-3 : 0
-2 : 14
-1 : 16
0 : 12
Explanation:
To get your answers, all you need to do is input the value of w that you are given into the equation of w^3 - 5w + 12.
An example of this, using the first value given:
Begin with w^3 - 5w + 12 and input the value -4 to make -4^3 - 5(-4) + 12
Simplify and solve the first parts of the equation,
-4^3 = -64 & 5(-4) = -20
This will give you -64 - (-20) + 12 / -64 + 20 + 12
Solve through by starting with -64 + 20 = -44, then -44 + 12 = -32.
All you need to do is continue the process with each value, for example the -2 value would make the equation -2^3 - 5(-2) + 12
-2^3 = -8 & 5(-2) = -10
-8 - (-10) + 12 = -8 + 10 + 12
-8 + 10 = 2 --> 2 + 12 = 14
