Question

write a polynomial function to model the data

Answer 1

ANY GUESS ON HOW TO DO THIS?

Answer 2

Show us @nincompoop

Answer 3

IDK MAN LOOKS TOUGH

Answer 4

f(x)=10,41667+0,34375*x+0,08807*x^2

Answer 5

count the number of times the function changes from increasing function to decreasing function or from decreasing function to increasing function. That will give the number of turning points of the function. That is, the number of extrema (maxima / minima). The degree of the polynomial should be one more than the number of extrema. Then try to model that degree polynomial to fir the given data using a calculator that has that capability or an online tool.

Answer 6

YOU USE A CALCULATOR @iambatman

Answer 7

LMAO

Answer 8

I had a feeling you'd say that lmao

Answer 9

YOU'D BE WASTING TIME DOING THIS MANUALLY... AND IN PRECAL CLASS CALCULATOR IS ENCOURAGED ANYWAY

Answer 10

I think the TI's can do this really well lol.

Answer 11

DEFINITELY
VIRTUAL TI'S OR EMULATORS

Answer 12

You have to tell the calculator what degree polynomial to fit and hence the step to count the number of turning points and adding one to that number to arrive at the degree of polynomial to fit.

Answer 13

you can test out different fit to see which one is good...
wolframalpha is good at this kind of crap

Answer 14

f(x)=10,41667+0,34375*x+0,08807*x^2 or I don't understand the task?

Answer 15

@AndreyZn: You have fitted a quadratic function. But there may be better fit with cubic or higher degree polynomials. Since the problem does not explicitly state what degree polynomial to fit I came up with one way to do it which will account for all the turning points in the data. A quadratic will have just one turning point and will not accommodate the rest of the turning points.

Answer 16

Is this for a statistics course that deals with regression equations?

Answer 17

no
