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...

You can also simply graph the polynomial and make a visual judgement. In the image below, the polynomial has a relative maxima at 2 and relative minima at 4 and -2. The relative minima at -2 is also a global minima; the absolute maxima doesn’t exist because the value of the polynomia...
We have two real roots and two complex roots. When you graph these polynomials, keep in mind the complex zeros are not x-intercepts. If a real root appears an even number of times, then the polynomial touches the x-axis. If a real root appears an odd number of times, then the polyno...

Zeros of a polynomial function A zero of a function is a value of {eq}x {/eq} that makes {eq}f(x) {/eq} equal zero. On the graph, a zero of a function appears as an {eq}x {/eq}-intercept. Let's use these steps, formulas, and definitions to work through ...
Polynomial functions have the domain of all reals. The range depends on the degree and leading coefficient. See: Polynomial functions. Square (quadratic) functions have a domain of all real numbers. The range depends on the sign of the leading coefficient: y ≥ min (+) or y ≥ max, (-...
Don't try to mix the two sets of definitions; it'll only confuse you.Just because all of the examples so far have involved polynomial functions, don't think that the concept of even and odd functions is restricted to polynomials. It's not. Trigonometry is full of functions that are ...
, and graph the function. Solution:The domain of a polynomial is the entire set of real numbers. The limiting factor on the domain for a rational function is the denominator, which cannot be equal to zero. The values not included in the domain oft(x) are the roots of th...
