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

• (3, -1)
• (0, 8)
• (4, 2)
