What is the zero of a graph?

Back

The zero of a graph is the x-value where the graph intersects the x-axis, meaning the output (y-value) is zero.

What is the equation for the total cost of a taxi ride that charges a flat fee plus a per-mile rate?

Back

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the range of a function given a specific domain?

Back

To find the range, substitute the values from the domain into the function and determine the resulting output values.

Front

What is the significance of the slope in a linear function?

Back

The slope represents the rate of change of y with respect to x, indicating how much y changes for a unit change in x.

Front

What does a negative slope indicate about a linear function?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship between the two variables.

Front

What is the meaning of the y-intercept in a linear equation?

Back

The y-intercept is the point where the graph intersects the y-axis, representing the value of y when x is zero.

Front

How do you determine the total cost for purchasing between 4 and 7 video games?

Back

Substitute x = 4 and x = 7 into the cost function to find the minimum and maximum costs.

Front

What is the definition of a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input from its domain.
