Teachers can browse by activities to find suitable picks to use in class or to set as homework. These include marble-sliding games that have students transform periodic functions by trying to slide marbles through points on a graph. Desmos can also be used as a four-function calculator...
To put this another way, every function in a family is a transformation of a parent function. For example, the function f(x) = 2x is the linear parent function vertically stretched by a factor of 2; Instead of the function passing through (1, 1) the graph passes through (2, 1): Co...
shown on the above graph, is completely above the x-axis, which means it is a positive function. However, notice that it is only increasing for function values on the right-hand side of the vertical axis; the function is decreasing for values to the...
Graphing calculators first came into existence in the 1980s. Today, you can now enjoy the same features and functionalities by simply using an online math problem solver. Many web-based graphing calculators allow students to graph complex equations in a single click. More impressively, however, yo...
students make accurate self-assessments, because (as Nell’s group has found in the past, with one paper described here) students tend to have inflated views of what they should be able to do, and when they can’t achieve those lofty goals, there is a negative impact on their self-...
Hot tip. Go to desmos.com and graph it. It really helps to see graphs and check your answers. You can click on zeros of the function and min/max as well. The graph shows that dy/dx >0 from pi/2 to pi and 3pi/2 to 2pi...
Homework Statement The figure shows the graph of a cubic polynomial. The function graphed is f(x)= Hint: You may write the function as f(x) =...
Since the 0 negates the infinity, the line has a constant limit. This would appear as a horizontal line on the graph. Back to Top Nonlinear Functions What is a Nonlinear Function? A nonlinear function is defined as one that isn’t a linear function. Graphically, a linear function is ...
In general, the easiest way to find cusps in graphs is to graph the function with a graphing calculator. Example: The function f(x) = x2/3 has a cusp at x = 0. This is shown on the following graph: A cusp is a sharp curve on a graph. Graphed with Desmos.com. The first deriv...
a graph at only one point and is practically parallel to the graph at that point. If you aren’t comfortable with drawing tangent lines,this Desmos toolwill give you some great practice. You can change the function and it will sketch the tangent line for any point “a” on the graph: ...
