How do you determine if a relation is a function?

Back

A relation is a function if every input (x-value) corresponds to exactly one output (y-value). This can be checked using the vertical line test on a graph.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

How do you find the value of x for a given function g(x)?

Back

To find the value of x for a given function g(x), set g(x) equal to the desired output and solve for x.

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

Back

The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept.

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

What is the y-intercept of a linear function?

Back

The y-intercept of a linear function is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

How can you determine the equation of a line of best fit?

Back

The equation of a line of best fit can be determined using statistical methods such as least squares regression, which minimizes the distance between the data points and the line.
