Given y = (x + 4)(x - 6), rewrite in vertex form (remember you will need to find the vertex for that...)

• y = (x - 1)² - 25

• y = (x + 1)² - 21

• y = (x + 4)² - 6

• y = (x - 6)² + 4

Determine which statement is true about the function:

f(x) = -x² + 2x - 10

• Opens upward, y-intercept is (0, -10)

• Opens upward, y-intercept is (0, 10)

• Opens downward, y-intercept is (0, -10)

• Opens downward, y-intercept is (0, 10)
