Solving for x intercepts

What are the 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 are the x intercepts of x²+9x+14

• 2, 7

• -2, -7

• 2, -7

• -2, 7

What are the x intercepts of the quadratic function?

y = x² - 2x - 15

• x = -2

  x = -15

• x = -3

  x = 5

• x = 3

  x = -5

• x = 1

  x = -16

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x -3 = y

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Use the quadratic formula to determine what are the solutions to x² - 3x -5= 0?

• 
• 
• 
• 

Determine what numbers you would plug in for a, b and c in the quadratic formula

y = x² +5x +7

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

What is this formula?

• This is the speed of light formula.
• This is the quadratic formula.
• This is the zero product property.
• This is scary.
