Question

Use a graphing calculator to find the coordinates of the turning points of the graph of each polynomial function in the given domain interval. Give answers to the nearest hundredth. ƒ(x)=2x^3-5x^2-x+1; [1.4, 2]

Accepted Answer

Or the following polynomial function with the specified domain, determine the coordinate of the turning point with the help of a graphene utility boundary and to the nearest hundreds. Our equation here is four X, the third minus seven X squared minus eight X plus two. And we're looking over the domain negative 1 to 1, we have four answers here which are points and to determine them, we need to graph our function first tells us to um use a graphing utility. So we'll plug it into a graphing calculator. I've plugged it in here and graphed out the equation for us. Now, the question asks us to find the turning point over the interval negative 1 to 1. Let's first go ahead and denote the interval on our graph. We have X equals negative one and X equals one as our bounce which are noted as vertical lens. So I'll put a vertical line at each of these values. Now, it was a turning point between these two lines. A turning point on a graph is just where our graph changes direction. For example, we notice here our graph is increasing or going up until it hits a certain point and then starts going down or decreasing. That would be our turning point. If we were to plug into our graphing calculator, we would see that our turning point occurs at negative 0.423 point 83. That means the answer to our problem turns out to be answer C OK. I hope to help you solve the problem. Thank you for watching. Goodbye.
