Algebra 2 Quadratic Forms

What information can I find from this form of the equation?

• x-intercepts: x = -5 and x = 12

• y-intercept: y = 12

• vertex: (-5, 12)

Convert the equation y= x² - 2x - 5 into vertex form.

• y= (x - 1)² - 6

• y= -(x - 1)² - 6

• y= (x + 1)² - 6

• y= -(x + 6)² - 1

Which of the following shows
f(x) = x² + 12x - 2
written in vertex form?

• f(x) = (x + 6)² + 142

• f(x) = (x + 6)² - 34

• f(x) = (x + 6)² - 38

• f(x) = (x + 6)² + 34

Find the zero(s) of the function.

• x = {-4, 4}

• x = -4
