Linear Functions
Find the slope and y-intercept of:
y=1/3x+7
Slope: 1/3
Y-int: (0,7)
f(x)=2(x-6)^2+3
right 6, up 3
The graph of f(x) = x^3 is translated 11 units up and 7 units left. Write the equation of the function.
f(x) = (x+7)3 + 11
What teams have won the most Super Bowls?
Pittsburgh Steelers and New England Patriots (6 each)
Find g(x), where g(x) is the translation 5 units right and 8 units up of(x)=x.
g(x)=(x-5)+8
Does this graph point up or down?
g(x)=-3x+x^2-7
points up
True or false: the following function is cubic
f(x) = -x3 + 2x - 9.
True
What famous jeweler makes the Lombardi Trophy?
Tiffany
There is a line that includes the point (0, 0) and has a slope of 5. What is its equation in slope-intercept form?
y=5x
What is the end behavior of:
f(x)=-3x^2
as x goes right, y goes down
as x goes left, y goes down
Factor x3 - 125 completely.
(x - 5)(x2 + 5x + 25)
