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?
"You got blood on your face, you big disgrace,
"Waving your banner all over the place."
What is "We Will Rock You?"
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?
"I've taken my bows
"And my curtain calls.
"You brought me fame and fortune
"And everything that goes with it.
"I thank you all."
What is "We Are the Champions?"
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?
"I see a little silhouetto of a man.
"Scaramouche, Scaramouche, will you do the Fandango?
"Thunderbolt and lightning, very, very frightening me.
"(Galileo) Galileo, (Galileo) Galileo, Galileo Figaro, magnifico."
What is "Bohemian Rhapsody?"
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?
"I gotta be cool, relax
"Get hip and get on my tracks
"Take a back seat, hitchhike
"And take a long ride on my motorbike."
What is "Crazy Little Thing Called 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?
"Another hero, another mindless crime
"Behind the curtain, in the pantomime.
"Hold the line.
"Does anybody want to take it anymore?"
What is "The Show Must Go On?"
