Again, as the power increases, the graphs flatten near the origin and become steeper away from the origin. The general rule is that for any n given points there is a function of degree whose graph goes through them. The end behavior indicates an odd-degree polynomial function; there are 3 \(x\)-intercepts and 2 turning points, so the degree is odd and at least 3. For equation solving, Wolfram|Alpha calls the Wolfram Language's Solve and Reduce functions, which contain a broad range of methods for all kinds of algebra, from basic linear and quadratic equations to multivariate nonlinear systems. Math can be a difficult subject for many people, but it doesn't have to be! How To: Given two points on the curve of an exponential function, use a graphing calculator to find the equation. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as \(x\) gets very large or very small, so its behavior will dominate the graph. This too is typically encountered in secondary or college math curricula. Steps for that are as follows: 1. The end behavior of the graph tells us this is the graph of an even-degree polynomial. Can Martian Regolith be Easily Melted with Microwaves.
