We just need to take care of the exponents of variables to determine whether it is a polynomial function.Polynomial Function GraphWe can represent all the polynomial functions in the form of a graph. Remember that the domain of any polynomial function is the set of all real numbers. The ...
Draw the graph of a polynomial function using end behavior, turning points, intercepts, and the Intermediate Value Theorem.We can use what we have learned about multiplicities, end behavior, and turning points to sketch graphs of polynomial functions. Let us put this all together and look at ...

For example, the quartic function f(x) = -2x4 + x3 – 5x2 – 10 has a leading coefficient of -2. The Leading Coefficient Test As x increases or decreases without bound, the graph of the polynomial function f (x) = anxn + an-1xn-1 + an-2xn-2 +…+ a1x + a0 (an 1 0)...
Graph the polynomial function. {eq}f(x)=(x-2)^2(x+1)^4 {/eq} Polynomial Function: A polynomial function in one variable is a linear combination of positive integer powers of the variable. That is a polynomial function is of the form: $$f(x) = a_n x^n + a_{n-1} x...
In your Algebra 2 class, you'll learn how to graph polynomial functions of the form f(x) = x^2 + 5. The f(x), meaning function based on the variable x, is another way of saying y, as in the x-y coordinate graph system. Graph a polynomial function using a graph with an x an...
