The polynomial remainder theorem states that if any given function f(x) is divided by a polynomial of the form (x - a), f(a) = the remainder of the polynomial division. What if there is a problem like (x-1)^3 (x+2)^2 will the multiplicity be the addition of 3 and 2 or the highest exponent will be the multiplicity? f_f(x)=4x^5-5x^3 , but also f_f(x)=3 Solve Now Here, we will be discussing about Write an equation for the 4th degree polynomial graphed below. Let's look at the graph of a function that has the same zeros, but different multiplicities. A simple random sample of 64 households is to be contacted and the sample proportion compu There can be less as well, which is what multiplicity helps us determine. The y-intercept is located at (0, 2). From this zoomed-in view, we can refine our estimate for the maximum volume to about 339 cubic cm which occurs when the squares measure approximately 2.7 cm on each side.

If a function has a local minimum at a, then [latex]f\left(a\right)\le f\left(x\right)[/latex] for all xin an open interval around x= a. Each x-intercept corresponds to a zero of the polynomial function and each zero yields a factor, so we can now write the polynomial in factored form. Math is all about solving equations and finding the right answer. Because a polynomial function written in factored form will have an x-intercept where each factor is equal to zero, we can form a function that will pass through a set of x-intercepts by introducing a corresponding set of factors. We will start this problem by drawing a picture like the one below, labeling the width of the cut-out squares with a variable, w. Notice that after a square is cut out from each end, it leaves a [latex]\left(14 - 2w\right)[/latex] cm by [latex]\left(20 - 2w\right)[/latex] cm rectangle for the base of the box, and the box will be wcm tall. We can use this graph to estimate the maximum value for the volume, restricted to values for wthat are reasonable for this problem, values from 0 to 7. When we are given the graph of a polynomial, we can deduce what its zeros are, which helps us determine a few factors the polynomial's equation must include. From the graph, the zeros of the polynomial of given graph Direct link to rylin0403's post Quite simple acutally. Math can be tough, but with a little practice, anyone can master it.
