Watch this quick tutorial to learn how: Who knew piecewise notation could be so fun! We will now see how Excel can be used to draw some trig graphs. The definite integral of a function over an interval [a, b] is the net signed area between the x-axis and the graph of the function over the interval. Not only was I incorrect, but Desmos responded to my blog to correct me! On the other hand, we also do this all the time in math -- even though technically something like f(x) = x/x isn't defined at x=0, we often extend the domain of f(x) when possible if there's a natural way to do so. Desmos.com - Use technology to graph quadratic functions and identify their key characteristics; 3.2 - Interpret Key Features of Quadratic Graphs in Context. Determine the interval(s) of the domain over which f has positive concavity (or the graph is "concave up"). Because is piecewise defined, and potentially discontinuous at , it is important to understand the behavior of near .
