Calculating Quadratics Practice

The vertex of this parabola is...

• (-4, -12.5)

• (12.5, 4)

• (-12.5, -4)

• (4, 12.5)

What is the vertex?

• (0, - 1)

• (0, 0.5)

• (-1, 0)

• (0.5, 0)

Find the Vertex:
f(x) = x² + 10x + 21

• (-5,-4)

• (1,10)

• (10,21)

• No Real Solution

What is the axis of symmetry for x² - 14x + 48

• x = -8

• x = -7

• x = -6

• x = 6

• x = 7

Select the solutions to the equation

4x² + 11x + 7 = 0

• x = - 1.75

• x = 6

• x = - 1

• x = 1

What are the solutions to the quadratic equation?

• x = -4

• x = 1

• x = -1

• x = 2

• x = 4

Solve using the quadratic formula.

• x = 7, x = 5

• x = 2, x = 1/3

• x = 6, x = 7

• x = 14, x= 13

Solve
x² + 13x + 12 = 0

• x = -1, x = -12

• x = -1, x = -24

• x = -2, x = -6

• x = -2, x = -12
