Question

Evaluate each expression for the given values of the variables 5X + 2Y^2-Y^3; x = 2 and y=4

what are they wanting me to reflect?

Answer 1

We are given the expression:

`5x+2y^(2)-y^(3)`

Now we have to determine the value of this expression at x=2 and y=4.

So let us plug the values of x and y in the expression:

`5(2)+2(4)^(2)-(4)^(3)`

`=10+32-64`

=-22

So on plugging x=2 and y=4 in the given expression we get the value as -22

Answer :
`5x+2y^(2)-y^(3)`=-22
