Quadratic Review Unit 2

Which of the following is not a quadratic expression?

For the following graph indicate whether it is a minimum or maximum turning point

• A) (4, 3)

• B) (3, 4)

• C) (-3, -4)

• D) (4, -3)

• E) (-3, 4)

The turning point of the graph ( y = (x - 5)(x + 5) ) will be at:

• (0, 0)

• (5, -5)

• (0, -25)

• (-5, 5)

• (-25, -10)

If the square of a number multiplied by 5, the answer is 125. Calculate the number.
