Functions

Front

What are the domain values in a function?

Back

The domain values are the x values.

Front

How do you find the x value when given a function f(x) and a specific output?

Back

Set f(x) equal to the output and solve for x.

Front

Write the equation for the total amount of money Pablo has after mowing x lawns if he starts with $12 and earns $7 per lawn.

Back

M(x) = 7x + 12

Front

What is the domain of a function?

Back

The domain is the set of all possible x values for which the function is defined.

Front

What is the range of a function?

Back

The range is the set of all possible y values that the function can output.

Front

If a function has a domain of -7 ≤ x < 5, what does this mean?

Back

This means x can take any value from -7 to just below 5.

Front

If a function has a range of -3 < y < 3, what does this indicate about the output values?

Back

This indicates that the output values y can be greater than -3 and less than 3.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line.

Front

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

Back

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

Front

How do you determine the slope of a line given two points?

Back

The slope (m) is calculated as (y2 - y1) / (x2 - x1).
