• (0, 4)

Which of the following equations matches vertex form of a quadratic?

• ax + by = c
• y = a(x - h)² + k

If given the equation y = 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)

Convert f(x) = 3x²+ 6x - 5 to vertex form.

• f(x) = 3(x + 1)² - 8

• f(x) = 3(x - 1) ² - 8

• f(x) = 3(x + 2)² - 8

• f(x) = 3(x - 2)² - 8
