Find the highest power of \(x\) to determine the degree function. In both cases, you could divide your first equation by the second one (or vice versa) and then take ln on both sides. Now, using the exponential property that (x^a)/ (x^b)= x^ (a-b), we have By taking the time to explain the problem and break it down into smaller pieces, anyone can learn to solve math problems. The mathematics power calculator is a simple maths calculator that tells you how much a number equals in its exponential form. If has degree , then it is well known that there are roots, once one takes into account multiplicity. eMathHelp: free math calculator - solves algebra, geometry, calculus, statistics, linear algebra, and linear programming problems step by step In L2, enter the corresponding y-coordinates. Determine whether the power is even or odd. (A number that multiplies a variable raised to an exponent is known as a coefficient. The end behavior of a polynomial function is the same as the end behavior of the power function represented by the leading term of the function. Clear any existing entries in columns L1 or L2. 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. The degree of a polynomial function helps us to determine the number of \(x\)-intercepts and the number of turning points.
