Write the intercept form in standard form:

y = 3(x+2)(x-1)

Hint: Expand and simplify

• 3x²+3x-6

• x²+x-2

What will be the line of symmetry for the following quadratic function:

y = -2(x+3)(x+9)

Hint: Use the factors to determine the x intercepts. Then use these intercepts to determine the axis of symmetry

• x = 6

• x = -6

• x = -9

• x = -3

Find the vertex:
f(x) = 3(x-2)(x+4)

• (-1, -27)
• (1, -15)

Use the graph to determine the zeros.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3
