What is the axis of symmetry?
y = 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
