In this problem, you can graph |2x-5| in Y₁ and 7 in Y₂. For example, there might be a problem like this: Students sometimes start solving algebraically and might miss that there are two possible solutions. When you are faced with an absolute value equation or an inequality problem on the ACT, it might be helpful to see the graph before starting to solve the problem. You can use this feature to assign or store values to a variable.Ĥ: Absolute Value – Discover Math Conceptually, Graphically, Visually This is possible by using the sto → key on the TI-84 Plus.

In the screenshot below, you can see an example on how to evaluate various expressions for A = – 4 and B = – 3. Sometimes you will need to evaluate expressions on the ACT. You can even evaluate the composition of functions like in the example.ģ: Evaluate Expressions Involving More Than One Variable Now that you know this trick, you can use it to do simple things like evaluating functions or take it to the next level and add, subtract, multiply and divide functions. You can find Y₁ and Y₂ by pressing the alpha key and then trace (f4). Then on the home screen, you can use that to do b(a(4)) in this case would be Y₂ (Y₁ (4)).

In Y₂, enter in the second function, x² +4. Press the y= key, then in Y₁ enter in the first function, 3x-2. You can store the functions in Y₁ and Y₂ to help you answer this question. For example, you might see a problem like this:

#Tips for the act plus#
You can save time by using a feature on the TI-84 Plus that you normally use to graph functions. On the ACT, you are often asked to evaluate functions and composition of functions. Once you switch your calculator to that mode, you can add, subtract, multiply, and divide complex numbers. Do this by pressing the mode key on your calculator and on the 7th row, you’ll see the a + bi (complex) mode. Below are 10 features on the TI-84 Plus that help students do their best work on the ACT.Ĭome across a problem that uses complex numbers? Fear not! You can change the TI-84 Plus into a + bi (complex) mode. You can use your TI graphing calculator to work through problems more efficiently, help verify answers, and model a difficult word problem. The TI-84 Plus graphing calculator is allowed during the entire portion of the math section of the ACT.* The questions get more difficult as the problem number increases, so you should aim to do questions #1-20 in 30 seconds each, #20-40 in 60 seconds each, and #40- 60 in 90 seconds each, on average. There are 60 questions on the math section of the ACT and you only have 60 minutes to complete them. If you are able to score a seat, here are my favorite features on the TI-84 Plus family of graphing calculators to leverage when taking the ACT. The ACT continues to add seats and sites as they work with local test centers to add capacity across the nation. This means continued limitations in test center capacity and inevitable cancellations throughout the remainder of the year. Unfortunately, it’s clear the global pandemic will be with us well into the winter.
