What are the zeros of the function

y= -4(x - 3)(x+5)?

• -12 and 20

• -5 and 3

• -4 and -5

• -3 and 5

What are the zeros of the equation y = x(x + 5)?

• 0, –5

• –5

• 0, 5

• 1, –5

Write the equation for the quadratic function shown in the graph.

• y = – 3 (x – 1)(x – 3)

• y = 3 (x – 1)(x – 3)

• y = 3 (x + 1)(x + 3)

• y = 3 (x + 1)(x – 3)

Which statement is true for the function
x² + 4x - 45

• The zeroes are -5 and -9 because the factors are (x + 5)(x +9)
• The zeroes are -5 and 9 because the factors are (x + 5)(x - 9)
• The zeroes are 5 and -9 because the factors are (x - 5)(x + 9)
• The zeroes are 5 and 9 because the factors are (x - 5)(x - 9)

What are the zeros of f(x) = x²+9x+14 and factored form?

• 2, 7 because f(x) = (x-2)(x-7)

• -2, -7 because f(x) = (x+2)(x+7)

• 2, -7 because f(x) = (x-2)(x+7)

• -2, 7 because f(x) = (x+2)(x-7)

What are the x-interepts for the graph of the function:  y = x² - 3x - 10 

• -5, 2
• -5, -2
• 5, -2
• 5, 2

How do you determine the y-intercept of any equation?

• set the y - value equal to zero

• set the x - value equal to zero

• average the zeros

• find the axis of symmetry

On a quadratic function, the axis of symmetry is x=5.  Which of these could be the x-intercepts?

• (5,0)(-5,0)
• (-3,0) (-7,0)
• (2,0) (8,0)
• (0,0) (5,0)

Which graph has the x intercepts of -2 and 1?

• y = 2x - 1

• y = x² - 2x + 1

• y = x² + x - 2

• y=x² - x - 2
