Arrange the quadratic function in standard form.

• 3x²

• +8

• -4x

Rewrite the quadratic function in standard form.

f(x) = (x - 2)(x + 4)

• x² - 2x - 8

• x² - 2x + 4x - 8

• x² + 2x - 8

• x² + 2x + 8

What does "a" respresent in a quadratic function? Select all that apply.

• "a" is the number by itself.

• "a" is the number in front of x

• "a" determines how the parabola opens

• "a" is the number in front of x².

What does "c" represent in the quadratic function? Select all that apply.

• "c" is the number by itself.

• "c" is in front of the x term.

• "c" tells you the x-intercepts of the quadratic.

• "c" tells you the y-intercept of the quadratic function.

What is "a" in the following quadratic function? (Hint: You may have to rewrite the function in standard form).

y = 3x(x + 5)

• 3

• 5

• 1

• 0

What is "c" in the following quadratic function? (Hint: You may have to rewrite the function in standard form).

Does this parabola open up or down? (Hint: You may need to rewrite in standard form first).

y = 3x² + 2x - 12

• Opens Up

• Opens Down

• Cannot Be Determined

What is a, b, and c for the following quadratic function. (Hint: You may need to rewrite in standard form).

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

• a = 2

  b = -3

  c = 2

• a = 2

  b = 1

  c = -6

• a = 2

  b = -1

  c = -6

• a = 2

  b = -7

  c = -6

What is the y-intercept of the following quadratic function:

g(x) = -3x² - 10x + 14

• (0, 14)

• (0, -14)

• (0, -3)

• (0, -10)

Rewrite the quadratic in standard form:

y = 2(x -1)² - 1

• x² - 2x + 1

• 2x² - 4x + 12

• 2x² - 4x + 1

• 2(x² - 4x + 12) - 1
