Question

Evaluate x3 - 3y when x = -3 and y = 4 what is this?

Answer 1

-39

Explanation:

The expression in this problem is

`3x^3 - 3y`

We want to evaluate this expression when

`x=-3`

`y=4`

Substituting into the expression, we find:

`(-3)^3 - 3(4) = \\-27 - 12 = \\-39`

Because

`(-3)^3 = (-3)(-3)(-3) = -27`

and

`3\cdot 4 = 12`

And this expression is a polynomial, which is an expression consisting of more than one algebraic terms (in this case, two of them)
