Describe how the graph of the function  $g\left(x\right)\ =\ -x^2+5$  is related to the graph of  $f\left(x\right)\ =\ x^2$  

• translation of  $f\left(x\right)\ =\ x^2$  up 5 units

• translation of  $f\left(x\right)\ =\ x^2$ to the right 5 units 

• translation of  $f\left(x\right)\ =\ x^2$  reflected over the x-axis and up 5 units

• translation of  $f\left(x\right)\ =\ x^2$  reflected over the x-axis and down 5 units

A parabola has a vertex at (-3,2). Where is the axis of symmetry?

• y = -2
• x = 3
• x = -3
• y = 2

A parabola has a vertex at (-1.5,12.5) and passes through (0,8). Solve for "a" and write the equation in vertex form.

Formula: f(x) = a(x - h)² + k

• y = -1.5(12.5 - 8)²

• y = 2(x + 0)² + 8

• y = -2(x + 1.5)² + 12.5

• y = 8(x + 1.5)² - 12.5

• None of the above

Which of the following statements are TRUE?

Select all that apply.

• The "a" value is positive.

• The y-intercept is positive.

• It has two zeros.

• The axis of symmetry is x = 1.

• The vertex is at (0, 5).
