Both of these are examples of power functions because they consist of a coefficient, \({\pi}\) or \(\dfrac{4}{3}{\pi}\), multiplied by a variable \(r\) raised to a power. 1 Answer Sorted by: 1 The steps seem to be good. Based on this, it would be reasonable to conclude that the degree is even and at least 4. The reciprocal of a number is a number which when multiplied with the actual number produces a result of 1 For example, let us take the number 2. One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary. 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. 5 Examples of Solving Equations in Excel. The interface is very simple and even the dumbest of people can use this app. Figure \(\PageIndex{2}\) shows the graphs of \(f(x)=x^2\), \(g(x)=x^4\) and and \(h(x)=x^6\), which are all power functions with even, whole-number powers.
