Question

Graph the polynomial function. Approximate all of the real zeros of the function.
f(x)=60x^4 - 89x^3 + 2x^2 + 23x + 4

Answer 1

@mathmate can you describe the steps using a graphing calculator as previously suggested by @phi? This questionn was reposted.

Answer 2

@Kevon18
Are you looking for instructions to plot on a TI 83 family of calculators?
I work with a TI-83, but higher families are similar.
If so, here's what you do:
1. turn on the calculator (bottom left button)
2. Clear (if necessary)
3. Press "y=" button (top left)
4. Enter the function on the first y= line. Press enter (bottom-right)
5. Press "window" (to the right of "y=")
6. adjust the size of the window (for this function, you could try the following settings:
- xmin=-5
- xmax=5
- ymin=-1000
- ymax=1000
- xscl=1 (default)
- yscl=1 (default)
- Xres=1
7. Press "graph" (top right)
It may take 2 seconds to show the graph, but it should display the graph of the given function.

Answer 3

I'm looking for Step by Step on how to do this question with the answer?

Answer 4

Have you graphed the function yet?

Answer 5

no, i need help!

Answer 6

Can you specify the help you need, given that the precise steps have been given above?

Answer 7

If you are not using the TI-family to graph, ..

You can graph the polynomial at wolframalpha.com or desmos.com .
Try approximating the roots from the graph.

Tip: The polynomial will factor if you want to get the real zeros in that manner.

TI-family loool i like it hahaha
