Graphs

100

This point is where a graph crosses the y-axis.

What is the y-intercept?

200

This is where a graph crosses the x-axis.

What are zeros/solutions/roots/x-intercepts?

300

This point is located 3 units left and 2 units up from the origin.

What is (-3, 2) ?

400

We calculate this by dividing the change in y by the change in x.

What is the constant rate of change?

500

You have to do this to the blank coordinate plane before graphing no matter what.

What is label or number?

Polynomials

100

The expression ax²+bx+c is in this form.

What is Standard form?

200

The highest exponent tells you this about a polynomial.

What is the degree?

300

This is coefficient of the term with the highest exponent.

What is the leading coefficient?

400

This is the part of an expression with no variable.

What is a constant?

500

This form of an expression uses parentheses to show the parts that multiply.

What is Factored form?

Functions

100

We use this instead of "y" when using function notation.

What is f(x)?

200

We usually use this form of a linear equation to graph.

What is y=mx+b ?

300

This function changes by multiplying or dividing by a common factor. 

What is an exponential function?

400

This function creates a graph in the shape of a "U" and has solutions called "zeros."

What is a quadratic function?

500

Evaluate the function f(x) = 2x² - 3x + 1 for f(4).

What is 21?

Statistics

100

This refers to the data point that appears the most.

What is the mode?

200

This refers to the middle of the data set.

What is the median?

300

This is calculated by adding up all the values in a data set, then dividing by the number of data points. It is also called an average.

What is the mean?

400

The difference between the maximum and minimum is called the _______ , while the difference between Q3 and Q1 is called the ________ .

What is the range? What is the interquartile range (IQR)?

500

This is the percent that represents the 3 out of 7 people in this room who prefer pineapple pizza. 

What is 43%

Systems

100

This kind of system has one solution where the lines intersect written as an ordered pair (x,y).

What is a linear system of equations?

200

This kind of system uses inequality symbols.

What is a system of inequalities?

300

We use this kind of line when graphing an inequality with the symbol < or > .

What is a dashed or broken line?

400

We shade ________ the line with the symbol > and ________ the line with the symbol < .

What is above? What is below?

500

This is where the solution set is in a system of inequalities.

Where does one shaded region overlap with another shaded region?
