Front

What is the equation to represent the total cost of snowboarding if the resort charges $15 per hour and $25 to rent a board?

Back

y = 15x + 25, where y is the total cost and x is the number of hours.

Front

How many solutions does a graph have if it is parallel to the x-axis and does not intersect the y-axis?

Back

No solutions.

Front

What type of function does a table represent if the differences between consecutive outputs are not constant?

Back

Nonlinear function.

Front

Back

48 bacteria.

Front

What is the RANGE of the function if the output values are limited to between -8 and 2?

Back

-8 ≤ y ≤ 2.

Front

What is a linear function?

Back

A function that can be represented by a straight line on a graph, with a constant rate of change.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What does it mean for a function to be nonlinear?

Back

It means that the graph of the function does not form a straight line and the rate of change is not constant.

Front

How do you determine if a function is increasing or decreasing?

Back

By analyzing the slope: if the slope is positive, the function is increasing; if negative, it is decreasing.

Front

What is the y-intercept of the equation y = 2x + 3?

Back

The y-intercept is 3.
