Quadratics Review

Does this parabola have a minimum or maximum and what is its value?

• minimum: 2
• maximum: 2
• minimum: 5
• maximum: 5

True or false:

The solution, root, and zero of a problem are all the same thing

• True

• False, because the solution and root are the same but the zero is different

• False, because the zero and root are the same but the solution is different

• False, they are all different

y=2x²-6x+1 is in what form?
