How do you determine the charge for using a piecewise function?

Back

To determine the charge, evaluate the function based on the number of terms used and apply the appropriate formula for that interval.

Front

What does the notation f(x) represent?

Back

f(x) represents the value of the function f at the input x.

Front

What does it mean for a function to be continuous at a point?

Back

A function is continuous at a point if the limit of the function as it approaches that point equals the function's value at that point.

Front

How do you evaluate f(1) for a given function?

Back

To evaluate f(1), substitute 1 into the function's formula and simplify.
