Question

What is the answer to this?

Answer 1

Answer:

Up

Step-by-step explanation:

Y= 1x^2 + 3x + 9

Y= Ax^2 + Bx + C

To determine which way a parabola opens just look at the coefficient (the number) of the x^2 - Always use the coefficient that is beside the x^2

So,  if the coefficient A is positive the parabola is opening upward

      if the coefficient A is negative the parabola is opening downward

Answer 2

Up

How??

• To determine whether a parabola graph will go up or down we need to see the coefficient of x² in the quadratic equation.
• If the coefficient is positive then graph will go up and if the coefficient is negative then the graph will go down..

In our case, The coefficient of x² is +1, so the parabola will open in the upward direction.
