Test Part Two

What do we call the graph of a quadratic function?

• parabola

• linear

• cubic

• sinusoidal

What are the

roots (x-intercepts) of the function

f(x)= (x - 2)(x + 3)?

• x = - 2 or x = 3

• x = 2 or x = -3

• The are no real roots

• x = 2 or x = 3

What is the vertex of this function?

• (0, -3)

• (1, -4)

• (-2, 5)

• {-1, 3}

Solve for the values of x:(x + 2)(x - 3) = 0 (a)  

• { 2, 3 }

• { -2, -3 }

• { 2, 3 }

• { -2, 3 }

Solve by factoring: x2 + 3x - 18 = 0 (a)  

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

• (x-3)(5x+ 2)

• (x+3)(5x+ 2)

• (x-3)(x +2)

• (x+3)(x+2)

• maximum

• minimum

• neither

• both
