What is the domain of the function?
*Hint: Domain is the set of all x-values included in the function.

• x≥3

• x≤3

• All real numbers

• -1≤x≤5

What is the range?

• -3 ≤ y < ∞

• -1 ≤ y < ∞

• All real numbers

• -∞ < y ≤ -1

Using your calculator, graph y = -3x² + 6x - 5 and identify the max or min.

• Max: (1, -2)

• Min: (1, -2)

• Max: (-2, 1)

• Min: (-2, 1)
