Analyze the outputs of functions for every input on the graph y = f(x),(y is the output and x is the input). If it is possible to express the function output with a formula involving the input quantity, then we can define a function in algebraic form. Evaluating functions is important, because we graph functions just like we graph other equations: by picking a few values of x, plugging them into the function, evaluating, drawing the points, and connecting the dots. The result is also a function of x. Remember, a function is basically the same as an equation. Since there are seven [latex]x[/latex]-inputs, that means we will evaluate the function seven times as well. In doing so, we get a solution that looks like this. . In this section, we will take a look at how to find the role of a variable in an expression. Note that the calculator finds h = f $\circ$ g and this is not the same as h = g $\circ$ f. Multivariate functions are supported, but the composition is partial to x (that is, limited to only x). button to get the resulting composite function h(x) = f [ g(x) ]. need to restrict the domain of the composite function so it is well defined.
