is considered a piecewise function.
which piece the function uses depends on what the input is.
if t is between 0 (inclusive) and 3 (exclusive), i.e. , then the function uses the piece (horizontal line at y=250)
if t is between 3 (exclusive) and 7 (inclusive), i.e. , then the function uses the piece (horizontal line at y=2000).
if you want to enter this into a ti84 calculator, you would enter the following:
(refresh if the below does not display properly)
basically multiply each piece by their constraints, and add the pieces together.
the < and ≤ symbols, and the operator you would find the test menu, which is above the math button ( you would find under 2nd > test > logic)
