Lesson: Vertex Form of a Parabola

After you watch the lesson above, try this practice problem
What is the vertex form of the function $x^2 +6x+2$ ?

$y=(x+3)^2 - 7$

$y = (x+3)^2 + 11$

$y=(x-3)^2 +11$

$y=(x-3)^2 - 7$

Lesson: Finding Equivalent Forms of a Quadratic Function

After you watch the lesson above, try this practice problem
Which of the following is an equivalent form of the function $y=x^2 + 2x -3$ ?
