Finding Vertex of a Parabola

Find the vertex: katex latex="y=2\left(x-5\right)+3"

• 2(-5, 3)

• (5, -3)

• (10, 6)

• (5, 3)

Answer explanation

When finding the vertex in vertex form, your equation is written  $y=a\left(x-h\right)^2+k$  , and your vertex is (h, k). But remember, you want the OPPOSITE of h in your equation.If you have  $y=\left(x+3\right)^2-6$  , then h = -3 and k = -6 making your vertex (-3, -6)

Find the vertex:

• (1, 4)

• (4, 1)

• (0, 0)

• Not enough information

Answer explanation

When using a graph to find the vertex, you are looking for the highest or lowest point on the graph. From there, follow the x-axis (left and right) and then the y-axis (up and down)

Ordered pairs are ALWAYS written as (x, y)

Find the vertex:

• (2, 1)

• (-2, 1)

• (1, -2)

• (-2, -1)
