What is the vertex of the quadratic function:
y = x² - 6x + 11?

• (3,2)
• (-3,-2)
• (-3,2)
• (3,-2)

What is the axis of symmetry of:y=2x²-4x+9

• x = 1
• x = -1
• x = -2
• x = 4

Is this a max or min?

• max
• min
• cannot be determined

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different
