The x-intercepts are your zeros of the function. It is every place where x is equal to zero. Which means for every parentheses, we need to equal x to 0 using an equation. After that, we just solve for x
x + 2 = 0
-2 -2
x= -2
x +3 = 0
-3 -3
x= -3
x-5 = 0
+5 +5
x= 5
So your x-intercepts are: -2, -3, 5
