Answer:
x = 3
Step-by-step explanation:
Given in the question an equation,

Step 1

so,

Step 2
cancel 2 on both sides of the equation

Step 3


Step 4

Step 5

Step 6
x/3 = 1
x = 3(1)
x = 3
Answer:
The answer is -2
Step-by-step explanation:
A constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. In this case, our constant in the expression is -2
Since this is a piecewise function, we will want to find the right equation to use. We want to find f(2) so we will find the equation to use when x=2. This will be the third equation because it is -2<=x<=2. We then plug 2 into x^2 -2. This will give us (2^2)-2 = 4-2 = 2.
