Wolfram|Alpha doesn't run without JavaScript. Some functions are limited now because setting of JAVASCRIPT of the browser is OFF. Be sure to enter something in each input box before clicking solve. There are many ways to improve your writing skills. The degree of the polynomial is the highest power of the variable that occurs in the polynomial; it is the power of the first variable if the function is in general form. As the input values $x$ get very small, the output values $f(x)$ decrease without bound. The $x$-intercepts are $(2,0)$,$(1,0)$, and $(4,0)$. Example $\PageIndex{12}$: Drawing Conclusions about a Polynomial Function from the Factors. A polynomial function consists of either zero or the sum of a finite number of non-zero terms, each of which is a product of a number, called the coefficient of the term, and a variable raised to a non-negative integer power. \Rightarrow c = \frac{1600}{1024} = \frac{25}{16} Example $\PageIndex{10}$: Determining the Number of Intercepts and Turning Points of a Polynomial.

Sorry I didn't mean the notation but if there were any actual steps that I could have skipped, which you both helped with so thanks. 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. As the input values $x$ get very large, the output values $f(x)$ increase without bound. In most cases, you'll do this by entering the first number, pressing the carrot ( ^) button, and entering the number to which you want to raise the first number. Example $\PageIndex{4}$: Identifying Polynomial Functions. In both cases, you could divide your first equation by the second one (or vice versa) and then take ln on both sides. We are talking about squares, cubes and higher exponential powers here. To determine its end behavior, look at the leading term of the polynomial function.
