Answer 1

y = ax² + bx + c

Question 2

What are parabolas?

Answer 2

Graph of quadratic relations

Question 3

What is the turning point form/vertex form? and what is the turning point?

Answer 3

y = a(x-h)² + k

Turning point (TP): (h,k)

can be gotten after completing the square of the general form of a quadratic equation.
