Algebra Unit 9 Review

What do we call the highest or lowest point of a quadratic?

• parabola
• vertex
• graph
• point

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

What is the axis of symmetry for the function

f(x) = 3x² - 6x + 4

• x = 1

• x = -6

• x = 2

• x = -1

True or false:
The root, x-intercept, and zero 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
