What's the Vertex Form?

100

y = x² + 16x + 71

y = (x + 8)² + 7

200

y = -x² - 14x - 59

y = -(x + 7)² - 10

300

y = x² - 12x + 46

y = (x - 6)² + 10

400

162x + 731 = -y - 9x²

y = -9(x + 9)² - 2

500

1/2(y + 4) = (x - 7)²

y = 2(x - 7)² - 4

What's the Axis of Symmetry?

100

f(x) = -3(x - 2)² - 4

x = 2

200

f(x) = 1/4(x + 4)² + 3

x = -4

300

f(x) = -2(x + 5)² - 3

x = -5

400

f(x) = (x + 2)² - 1

x = -2

500

f(x) = 1/4(x + 5)² + 2

x = -5
