Question

If Y equals 31+ X to the power of two find the value of Y when X equals -2

Answer 1

The value of Y when X equals -2 is calculated by squaring -2 to get 4, then adding that to 31, resulting in Y being 35.

Step-by-step explanation:

To find the value of Y when X equals -2, we substitute -2 for X in the equation Y = 31 + X2.

• First, square the value of X: (-2)2 = 4.
• Next, add this result to 31: 31 + 4 = 35.
• So, the value of Y when X equals -2 is 35.

In mathematical terms, Y = 31 + (-2)2 = 31 + 4 = 35.
