Chapter 1: Introduction to Functions and Graphs
A number written in the form a * 10b, where 1<a<10 and b is an integer, is in this type of notation.
What is scientific notation?
This number of points uniquely determines the equation of a line.
What is two?
This is the name given to the highest (or lowest) point on the graph of a quadratic function.
What is the vertex?
A quadratic function will cross the x-axis at most this number of times.
What is two?
"Oh, can't you see me standing here?
"I got my back against the record machine.
"I ain't the worst that you've seen.
"Oh, can't you see what I mean?"
What is "Jump?"
The formula for the distance between two points is based on this famous theorem.
What is the Pythagorean Theorem?
Given the area A of a triangle and the base length b of the triangle, this formula gives the height h of the triangle.
What is h = 2A/b?
This quantity tells the type of solution a given quadratic equation possesses.
What is the discriminant?
This type of function f is such that f(-x) = -f(x).
What is an odd function?
"She's runnin', I'm flyin'
"Right behind in the rearview mirror now
"Got the fearin', power steerin'
"Pistons poppin', ain't no stoppin' now"
What is "Panama?"
This is the set of numbers that can be written as a/b, where a and b are both integers, a/b is in simplest form, and b is not equal to 0.
What is Q/the set of rational numbers?
These are the possible values of x if 6 - x > 4x + 1.
What is x < 1?
This is the simplified form of the square root of x2.
What is |x|?
In the function f(x) = 1/x, you will find this at x = 0.
What is a vertical asymptote?
"Pretty woman, walking down the street,
"Pretty woman, the kind Id like to meet,
"Pretty woman, I dont believe you it must be true,
"No one could look as good as you"
What is "(Oh) Pretty Woman?"
What are the domain and range?
If an object that weighs 100 pounds on Earth weighs 16.53 pounds on the moon, then another object that weighs 40 pounds on Earth weighs this much on the moon.
What is 6.61 pounds?
These are the possible values for x if x2 - 4 > 0.
What is x < -2 or x > 2?
This line is the horizontal asymptote of f(x) = (3x2 + 1)/x2.
What is y = 3?
"You look at every face in a crowd
"Some shine and some keep you guessin'
"Waitin' for someone to come into focus
"Teach you your final love lesson"
What is "When It's Love?"
The average rate of change represents this quantity of a linear function.
What is the slope?
These are the possible values for x if |2x - 5| < 7.
What is -1 < x < 6?
g(x) is the graph of f(x) = x3 when the graph is shifted to the right by 3 units and reflected across the x-axis.
What is g(x) = -(x - 3)3?
This is the solution to 3/(3x + 4) = 1.
What is x = -1/3?
"Questions deep within your eyes
"Now more than ever, you realize"
What is "Love Walks In?"
