Solving Quadratics Transformations

Which function has a translation of 2 units right and a vertical stretch by a factor of 5?

• f(x)= 5(x - 2)²

• f(x) = 5(x + 2)²

• f(x) = (x - 2)² - 5

• f(x) = (x + 2)² + 5

• F

• G

• H

• J

What is the vertex of the following equation:
y=-3(x-2)² - 4?

• (-2,-4)

• (2,-4)

• (3,-4)

• (2,4)

How did we transform from the parent function?

y = -1/5x² + 7 (Choose ALL that apply.)

• reflection over the x-axis

• vertical shift up 7

• vertical stretch of 1/5

• vertical shift down 7

• vertical compression of 1/5

What is this formula?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3
*remember right side should =0

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve by using the quadratic formula.

7x² - 26x - 8 = 0

• x = -1 and x = -7/8

• x = 4 and x = -2/7

• x = -4 and x = 2/7

• x = 4 and x = -7/2

2x² + 7x - 15 = 0

• x = -1.5 and x = 5

• No Solution

• x = -5 and x = 1.5

• x = 0.7 and x = 5

Solve for x. Round to the nearest hundredth if necessary.

3x² = 16x + 12

• x = -0.67 and x = 6

• x = -6 and x = 0.67

• x = 3.33 and x = 18

• x = -3.33 and x = 18
