The value of the expression for these values is 14.4

Step-by-step explanation:

We have the following expression

$xy^{2} - y^{3}$

We have to find the value when:

x = 8.8, y = -1.2

So we replace x and y by these values. So

$8.8*(-1.2)^{2} - (-1.2)^{3} = 14.4$

The value of the expression for these values is 14.4
