What is the absolute value function?

Back

The absolute value function, denoted as f(x) = |x|, returns the non-negative value of x. For example, |3| = 3 and |-3| = 3.

How do you simplify a complex fraction?

Back

To simplify a complex fraction, multiply the numerator and the denominator by the least common denominator (LCD) of the fractions involved.

What are domain restrictions in a function?

Back

Domain restrictions define the set of input values (x-values) for which a function is defined. For example, if a function has a denominator, the values that make the denominator zero are excluded from the domain.

How do you find the slope of a line?

Back

The slope of a line is calculated as the change in y divided by the change in x (rise over run). It is often represented as m in the slope-intercept form of a line, y = mx + b.

Front

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.

Front

What is the equation of a line with slope 3 and y-intercept 5?

Back

The equation is y = 3x + 5.

Front

What does it mean for a function to be piecewise defined?

Back

A piecewise defined function is a function that has different expressions or rules for different parts of its domain.
