Pleaseeeeee help :))) I only need help with #7 because i am confuseddd

steps below and attachment

Step-by-step explanation:

5. attachment 1: red font values would be changed

6. 2nd attachment: g(x) = (x+3)²-9

   3rd attachment: h(x) = |g(x)|

7. -8≤x≤-6 or 0≤x≤2    g(x) = (x+3)²-9

  -6≤x≤0    f(x) = - (x + 3)² +9

A change from 55 to 77 represents a positive change (increase) of 40%.

Hope this helps!
