Step-by-step explanation & ANSWER BELOW IS IN BOLD:
Given the value of x, we can substitute the function rule.
Let's solve these problems together.
Note : Negative * Negative = Positive
If x= -4, then y = 11 because

If x = -2, then y = 7 because

If x = 0, then y = 3 because

If x = 2, then y = -1 because

Hope this helps :)
Have an awesome day!
