Answer:
f(x) = (x - 4)² - 4
Step-by-step explanation:
∵ The general form of the Parabolic function is :
f(x) = (x - h) + k ⇒ where point (h , k) is the turning point
∵ The turning point is (4 , -4)
∴ f(x) = (x - 4)² + -4 = (x - 4)² - 4
To check the answer:
Use the point (6 , 0) ⇒ 0 = (6 - 4)² - 4 ⇒ 0 = 4 - 4
∴ f(x) = (x - 4)² - 4
