11.28 Vertex Form and Transformations

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

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Write the equation of the quadratic given the vertex and a point that the parabola goes through

Vertex: (4,-2)

Point:(2,6)

• y=2(x-4)²+2

• y=2(x-4)²-2

• y=2(x+4)²-2
