Question 1 of 9

Which of the following is the equation of the quadratic function below?
-10
10
10

Answer 1

B

Explanation:

The zeros ( where the graph crosses the x- axis ) are x = 2 and x = 6

The corresponding factors are (x - 2) and (x - 6) and the equation is the product of the factors, so

y = (x - 2)(x - 6) ← expand using Foil

y = x² - 8x + 12 → B
