Questions & Answers

Q: How do you start graphing a piecewise function on a TI-84 calculator?

To start, press the y= button on your calculator and enter the first equation or expression in the form X + 1, using parentheses if necessary.

Q: How do you enter a division symbol for a piecewise function on a TI-84 calculator?

To enter a division symbol, use the division sign on the keyboard after typing the equation or expression, followed by the divisor in parentheses.

Q: How do you graph an inequality like X ≤ -3 on a TI-84 calculator?

To graph an inequality like X ≤ -3, press the second button followed by the test button. Scroll down to find the less than or equal to option and press enter. Then enter the value -3.

Q: How do you graph a compound inequality on a TI-84 calculator?

To graph a compound inequality like X > -3 and X < 1, use the test option for greater than (-3) and the logical "and" operator from the logic menu, followed by the test option for less than (1).
