Factoring
Factor this function:
y = (3x^2 + 9x)
y = 3x(x + 3)
What is the parent quadratic function?
y = x^2
Where is the vertex of the parent quadratic function,
y = x^2 ?
What are the first 5 digits of pi ?
3.1415
Factor this function:
y = 64x^2 - 8x
y = 8x(8x - 1)
What is vertex form of a quadratic function?
y = a(x - h)^2 + k
Which value (h or k) indicates horizontal translation?
h
vertex form: y = 1(a - h) + k
Name an element on the periodic table that is a liquid at room temperature
Mercury
Bromine
y = x^2 + 13x + 22
y = (x + 11)(x + 2)
What is standard form of a quadratic function?
y = ax^2 + bx + c
At what point (x,y) is the vertex of this quadratic function?
y = (x - 2)^2 + 1
(2, 1)
What is the formula to find the axis of symmetry of a quadratic function? (from standard form)
From standard form: y = ax^2 + bx + c
h = -b/2a
therefore, x = h is the axis of symmetry
y = 9x^2 - 64
y = (3x - 8)(3x + 8)
What must be done to a quadratic function to flip it? (open upwards instead of downwards, or vise versa)
ex.
y = x^2 + 4x + 2 opens upward: a = 1
y = -x^2 + 4x + 2 opens downward: a = -1
What is the y-intercept of this function? Answer in the form (x, y)
y = x^2 + 10000000x + 2
(0, 2)
What color is Mr. Bowman's laser light?
y = 4x^2 - 40x + 100
y = (2x - 10)^2
y = x^2 + 2
y = 1(x - 0)^2 + 2
Write a function that translates the parent quadratic function 2 units left, and 5 units down.
y = (x + 2)^2 - 5
