Using the graph of y = -1.5x² + 12x - 23 shown here, what are the values of x when y = -5?

• x = 4

• x = 2, 6

• x = 3.2, 4.8

• cannot be determined on the graph

Which quadratic graph opens upward?

• y = 3x² – 4x – 1 

• y = -3x² – 1

• y = -x²

• y = -x² + 3x + 2

How do you determine if a quadratic function opens upward or downward?

• Look at the coefficient of the quadratic term (x^2)

• Look at the constant term (x^0)

• Look at the exponent of the quadratic term (x^2)

• Look at the coefficient of the linear term (x^1)

Tell whether the graph the quadratic function opens upward or downward.

• Upward

• Downward

What determines if a quadratic function opens up or down?

When does a quadratic open downward?

• when a is positive

• when a is negative

• it never opens downward

• when there is no b term

A negative quadratic will open.....

• upward

• downward
