Front

What is a function rule for the total cost of a pizza with t toppings if the base pizza costs $12.00 and each topping costs $1.50?

Back

C(t) = 1.5t + 12

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form y = ab^x, where a is a constant, b is the base, and x is the exponent.

Front

What are the horizontal and vertical scales in a graph?

Back

Horizontal = 0.5; Vertical = 2

Front

How do you represent a situation with a system of equations?

Back

Identify the variables and relationships, then write equations based on the information given.

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.

Front

What is the difference between linear and exponential growth?

Back

Linear growth increases by a constant amount, while exponential growth increases by a constant percentage.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.
