Features of exponential and logarithmic functions worksheet for Precalculus

Precalculus reads the same features with more attention to reflections and shifts: the y-intercept and asymptote of an exponential, the asymptote, domain and x-intercept of a logarithm, and domain and range written as inequalities. A negative a flips an exponential below its asymptote, which turns the range into y < k.

Also taught in Algebra 2, at its own level and with its own examples.

How to do these

Find the $y$ -intercept, the asymptote and the range of $y = - 3 \cdot 2^{x} + 6$

At x = 0 the power is 1, so y = -3 + 6 = 3.
As x heads to negative infinity, 2ˣ shrinks to 0, so y levels off at 6.
The -3 puts the curve below that line, so every y is less than 6.

The answer is $(0, 3)$ , $y = 6$ , range $y < 6$ .

Where students go wrong

Giving every exponential the range y > k. When a is negative the curve sits below its asymptote, so y = -3·2ˣ + 6 has range y < 6.

Also called asymptotes of exponential functions, domain of a logarithm, intercepts of exponential and log graphs or end behavior of exponentials.

What you can put on this worksheet

The y-intercept and the asymptote: Find the $y$ -intercept and the asymptote of $y = 3 \cdot 4^{x}$ → $(0, 3)$ , $y = 0$
Asymptote and domain of a logarithm: $y = \log_{4} (x - 1)$ . What are the asymptote and the domain? → $x = 1$ , domain $x > 1$
Domain, range, growth or decay: For $y = 2 {(1.5)}^{x} + 1$ , state the domain, the range, and whether it shows growth or decay. → domain all real numbers; range $y > 1$ ; growth

Questions about these worksheets

Yes. Every features of exponential and logarithmic functions sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Precalculus is usually taken around 11th or 12th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the features of exponential and logarithmic functions questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 3: the y-intercept and the asymptote, asymptote and domain of a logarithm and domain, range, growth or decay. Tick as many as you want and set how many of each, or let it spread them evenly.

Putting the log asymptote at x = 0 whatever the shift. It sits wherever the inside of the log becomes zero.
