The function f(x) = x^2 is called the

The ----------------is f(x0 =ax^2 + bx + c.

Explain how you can tell whether a functionof the form f(x) = ax^2 has a minimum or maximum value and what that value is.

Does this graph in the back have maximum or minimum value?

• maximum
• minimum
• neither
• both

What is the axis of symmetry for the following equation?
y=4x²-8x+9

• x=-8
• x=1
• x=-1
• x=2

What is the y intercept for the equation:
y = -8x² + 3x - 7

• (0, -8)
• (0, 3)
• (0, 7)
• (0, -7)

If given the equation
y = 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Which equation best represents the graph?

• y = 2(x - 4)² + 5
• y = 2(x + 4)² + 5
• y = -2(x - 4)² + 5
• y = -2(x + 4)² + 5
