The zeros of the function f(x) = 3x² – 3x – 6 are

• – 1 & – 2

• 1 & – 2

• 1 & 2

• – 1 & 2

Which equation represents a quadratic function?

• y = x + 2

• y = |x + 2|

• y = x²

• y = 2^x

If the roots of a quadratic equation are – 2 & 3, the equation can be written as

• (x – 2)(x + 3) = 0

• (x + 2)(x – 3) = 0

• (x + 2)(x + 3) = 0

• (x – 2)(x – 3) = 0

The graph of f(x) is shown.

Based on this graph, what are the roots of the equation f(x) = 0 ?

• 1 & – 5

• – 1 & 5

• 2 & – 9

• – 1 & – 5 & 5

For which equation is the solution set {– 5 , 2}?

• x² + 3x – 10 = 0

• x² – 3x = 10

• x² + 3x = – 10

• x² – 3x + 10 = 0
