Change the window of your graph so I can see how much money you will make over 30 years. Return to Exercises. With those informations you can assemble a function (squared if parabolic, linear if it's a straight stroke or exponential if it's funky) and if you then restrict it with an intervall, you can replicate that specific area of the stretch. 2: 7-21 Student eTool (Desmos) CCA 7. at first, has a lower rate of growth than the linear equation f(x) =50x; at first, has a slower rate of growth than a cubic function like f(x) = x 3, but eventually the growth rate of an exponential function f(x) = 2 x, increases more and more -- until the exponential growth function has the greatest value and rate of growth!. It forces students to create a t-table (with x-values already supplied), and then a graph for an exponential growth function. A linear function has the following form. Undo: ctrl + z. I just made my first Marbleslides in Desmos! It was incredibly easy, and the students said it was a really fun way to learn. A two-argument form giving is also implemented as Erf[z0, z1].

Use the links or image on each slide to take you to a Desmos page where you can use the sliders to explore how the graphs change. The logarithmic function is defined as the inverse of the exponential function a property that you may explore: Logarithmic Function and its Inverse the Exponential - HTML5 applet For B > 0 and B not equal to 1, Note: The logarithm to the base e is written ln(x). As a result, the pictures on the screen are not something that your browser can easily print. In these cases, "a" is used to represent a list or table header previously defined by the user in the calculator. I tell them that once we get to the lab they need all the time they can get to input functions into Desmos and mess with colors. So, an initial value of -2, and a common ratio of 1/7, common ratio of 1/7. Algebra 2, Math Activities, Student Engagement, Functions.
