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?

We are given the expression:

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:

=-22

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

Answer : =-22

24/56=hx^7

step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
