Representing, Naming, and Evaluating Functions

Front

What is the parent function of absolute value?

Back

The parent function of absolute value is f(x) = |x|.

Front

What is the range of the function s = 3t + 1 when the domain is {2, 4, 6}?

Back

The range is {7, 13, 19}.

Front

What is the independent variable of a function?

Back

The independent variable is the input of the function.

Front

What is the parent function of linear functions?

Back

The parent function of linear functions is f(x) = x.

Front

Write a function that tells how far d from their own goal line a football team will be as a function of plays p, given they average 4.5 yards/play and start on their own 20 yard line.

Back

d = 4.5p + 20.

Front

What is a function?

Back

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

Front

What does the term 'domain' refer to in a function?

Back

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

Front

What does the term 'range' refer to in a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

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

Back

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

Front

How do you evaluate a function at a specific input?

Back

To evaluate a function, substitute the input value into the function's equation.
