How has the function f(x)=|x|+4 been transformed? (Be specific! Which direction, how much?)
Vertical shift up 4
The domain of the blue function below.
The meaning of "one-to-one".
What is each y-value only occurs once?
f(5) using the piecewise defined function below
What is 1?
You can tell something is a function due to this rule.
What is each input has only one output?
An equation for the graph provided. Note: There has been NO stretch or shrink- just shifts/translations.
What is f(x)=(x-3)2-2?
f(x)=x+5 and g(x)=|x-6|. Evaluate f(g(2))
What is 9?
When given a graph, this test will tell you if the INVERSE is a function.
What is the horizontal line test?
On which domain is the piecewise defined function a quadratic?
What is (-infinity, 1]?
When given a graph, this test will tell you if it is a function.
What is the vertical line test?
The equation for a cubic function that has been shifted left 6, up 5, and has a vertical stretch of 2.
What is f(x)=2(x+6)3+5?
f(x)=x2 and g(x)=x+9. The domain of the function below in either set, interval, or algebraic notation.
g(x)/f(x)
What is (-infinity, 0) U (0, infinity)
Given the situation, determine if this is one-to-one.
"Each employee has their own desk"
Yes, it is one to one
f(-2) using the piecewise defined function below
What is 3?
The following terms can be grouped into 2 groups:
input, domain, independent, range, f(x), output, x, dependent
What are...
Group 1: Input, domain, x, independent
Group 2: Output, range, y, dependent
The graph below is this type of function (even or odd) because of this property (how do you know?)
Odd. It is rotated around the origin.
If f(x)=x3 and g(x)=1/x, this is g(f(x)).
What is
g(f(x))=1/x^3
Given the graph of the function f(x) below, is f-1(x) also a function?
No, it is not one-to-one (fails the horizontal line test)
A piecewise defined function such that the graph is linear on (-infinity, 2] and cubic on the interval (2, infinity)
Answers Vary. See the example below:
The domain and range of the function: f(x)=|2x|
The way to test if a function is even or odd is to do this.
Replace x with -x and see if the output is the same (even), opposite (odd), or neither.
f(x) is given by the graph below. g(x)=6x. What is g(f(1))?
What is 12?
What is the inverse of
g(x)=sqrt(x+3)
What is
x=y^2-3
g^-1(x)=g(x)^2-3
A piecewise function for the situation below:
"Ms. Beal's rock climbing membership costs $60 a month. She can go for up to 20 hours. Every hour over this costs $5 per hour."
What is
The average rate of change of f(x)=x2 on the interval [-2, 2]
