Your teacher gives you an equation in vertex form. If the "a" value is -3, select the statements below that are true.

• "a" will be -3 in standard form

• "a" represents a vertical compression

• "a" will become 9 in standard form

• the parabola will open downward

• "a" describes the horizontal shift

To find the vertex of a quadratic in standard form, you ​ (a)   and ​ (b)   . Then you ​ (c)   the value back into the ​ (d)   to find the ​ (e)   coordinate of the vertex.

• take the opposite of b

• divide it by 2

• substitute

• equation

• y

• x

• take the opposite of c

• multiply it by 5

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

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)
