Algebra 1 Test 11: Parabola

The axis of symmetry line passes through which point?

• y-intercept
• any random point
• vertex
• symmetrical point for the vertex

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

• y = -2
• x = 3
• x = -3
• y = 2

Use the graph to determine the solutions.

• -1 and -3
• 1 and -3
• 1 and 3
• -1 and 3

What is the vertex of the graph?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

What is the green dashed line called?

• roots or x-intercepts
• parabola
• axis of symmetry
• y intercept

What is the formula for this quadratic equation?

• y = -(x+0)(x+4)

• y = (x+0)(x+4)

• y = (x+0)(x-4)

• y = -(x+0)(x-4)

What is the equation of this graph?

• f(x) = -1 (x-3)(x+1)

• f(x) = -2 (x+3)(x-1)

• f(x) = -1/2 (x+3)(x-1)

• f(x) = -1/2 (x-3)(x+1)

Does the equation open up or down? 
Y = -3x² +7x - 2

• up
• down
• Neither; it opens to the right.
• Neither; it opens to the left.

What are the x-intercepts of the function?

y=(x-4)(x-2)

• x=4 and x=2

• x=-4 and x = -2

• x = 4 and x= -2

• x = -4 and x = 2

Find the intercept form equation for:

f(x) = 2x²- 16x + 30.

• f(x) = 2 (x-8)(x+15)

• f(x) = 2 (x+3)(x+5)

• f(x) = 2 (x-3)(x-5)
