What is another word for zeros?

• y-intercepts
• roots
• vertex
• axis of symmetry

What are the x-intercept/s of the function? 

• {x|x = 3}
• {x|x =-3,3}
• (3, 0)
• (-3, 0)&(3, 0)

True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation 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
