Draw me a graph/coordinate plane with the following labels:
Y-axis
X-axis
The 4 quadrants (ex. Q1, Q2, etc.)
The "origin"
Sample answer:
Determine whether the following is a function or not:
Not a function; would not pass the vertical line test
y=4x+6
x=-2, y=-2
x=-1, y=2
x=0, y=6
x=1, y=10
x=2, y=14
Write an algebraic expression for the following:

Determine whether this is a function or not
It is not a function!
When x=4 there are two outputs (y-values)
Determine whether the following is a function or not:
It is a function
What is a function?
A function is an equation/graph that represents the relationship between x/y, domain/range, input/output
Evaluate the following expression:
-4(5-2t)
-20+8t
Solve the following
z=63div(3^2-2)

The graph represents the height of a bungee jumper
Sample Answer:
The bungee jumper was standing for awhile, jumped and had an extreme drop in how high up they were. They bounced back up and down two more times before settling down fully
Identify the intercepts and determine if the symmetry of the following function:
X-Intercept: x=1.5
Y-Intercept: y=3
Symmetry: Not symmetrical (not a mirror of itself)
Solve the following
f(-4)=2x+4
f(-4)=-4
Rewrite the Expression
(8-3p)(-2)
-16+6p
Find the solution set of the equation if the replacement set is x:{1, 3, 5, 7, 9}
3x-11=16
{9}
Determine the domain and range of the following relation:
(2,5) , (-1,3) , (0,-1) , (3,3), (-4, -2)
Domain: -4, -1, 0, 2, 3
Range: -2, -1, 3, 5
If asked to describe the end behavior and extrema of a function, what 7qualities is the problem asking you to describe?
Where the function is positive (above the x-axis)
Where the function is negative (below the x-axis)
Where the function is increasing (left to right)
Where the function is decreasing (left to right)
The relative maximum
The relative minimum
End Behavior
If f(x)=6x+7 and g(x)=x2-4, find f(2)+g(2)
f(2)+g(2)=19
A video store chain has three locations. Use the information in the table below to write and evaluate an expression to estimate the total number of DVDs sold over a 4-day period.
4(145+211+184)
2160
(3 xx 5)t+(21-12)=15t+3^2
all real numbers!
Express the following relation as a mapping, table, and graph
(0,2) , (1,3) , (2,4) , (3,5)
Identify the intercepts, relative maximum, relative minimum, and describe the function's end behavior
X-Intercept(s): x=-3, x=-1, x=1
Y-Intercept(s): x=-3
Relative Maximum: 1
Relative Minimum: -4
End Behavior: As x decreases, the function decreases, as x increases, the function increases
(End behavior is looking at x increasing or decreasing on either end and determining if the graph is increasing or decreasing)
Solve 3[f(t)]+2 if f(t)=2t3
