What is the standard quadratic form?

• $y=mx+b$
  

• $y=ax^2+bx+c$
  

• $y=a\left(x-h\right)^2+k$

What are the green dots called?

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
