Consider a quadratic polynomial function f(x) = x2 + 2x - 5. To find its zeros:Set f(x) = 0. Then x2 + 2x - 5 = 0. Solve it. Here a = 1, b = 2 and c = -5. Let us use the quadratic formula to find the quadratic
Describe a polynomial function that could represent the graph. (Indicate the degree of the function and the sign of its leading coefficient.) Fill in the blanks. The ___ is used to determine whether the graph of an equation is a function of y in terms of x. Ide...

Knowing the degree of a polynomial function is useful in helping us predict what its graph will look like. 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...
Write the equation of a polynomial function given its graph.Now that we know how to find zeros of polynomial functions, we can use them to write formulas based on graphs. Because a polynomial function written in factored form will have an x-intercept where each factor is equal to zero, we...
Analyze the following polynomial function and sketch its graph. You may assume that it reaches extreme values atx=−2and0. g(x)=(x+2)2(1−x) Extremes and Behavior of the Function: When we analyze a function, we must know it...
Therefore, this is the graph of a quartic polynomial function or a polynomial of degree 4. Turning points can be maxima and/or minima. A global minimum, also called absolute minimum, is a point on the graph where the function has its smallest value. The point shown in blue is a global...
