What is the definition of a function?

• A function is a relation that assigns exactly one output for each input.

• A function is a set of ordered pairs with no restrictions.

• A function is a mathematical operation that can be reversed.

• A function is a type of graph that shows relationships between variables.

What does it mean for a function to be increasing?

• A function is increasing if, as the input values (x) increase, the output values (y) also increase.

• A function is increasing if the output values (y) decrease as the input values (x) increase.

• A function is increasing if it has a constant output regardless of the input values.

• A function is increasing if it oscillates between increasing and decreasing values.

What is the definition of a vertical asymptote?

• A vertical line that a graph approaches as the input approaches a certain value.

• A horizontal line that a graph approaches as the output approaches a certain value.

• A point where the graph intersects the x-axis.

• A line that represents the maximum value of a function.

All exponential functions have a ____________ asymptote

• vertical

• oblique

• horizontal

• circular

What is the difference between a linear function and a non-linear function?

• A linear function has a constant rate of change and graphs to a straight line, while a non-linear function does not.

• A linear function can have curves, while a non-linear function is always straight.

• A linear function is always increasing, while a non-linear function can decrease.

• A linear function has varying rates of change, while a non-linear function has a constant rate of change.

What is the quadratic formula?
