I am having a little trouble understanding what this question is asking me. Are there any graphing calculators online?
Do they want me to plug those numbers into the formula?
we have to use the graph of your function
I don't know if the link will work but that's the graph I plugged in
you have to count the intersection points
please I redraw the graph, please wait
for example y=-3 (green horizontal line) give us only one intersection point between the vertical lines at x=-3 and x=3, so we have only one solution
oh so all those numbers are on the y axis 20, -3, 2, -40, and 1
y=20 (blue horizontal line) gives us only one intersection point between the vertical lines at x=-3 and x=3, so, again, we have only one solution
simlarly with others values y=2, -40, 1
what graphing calculator is the one your using?
it is "desmos": https://www.desmos.com/calculator
ok I going to try the other ones
y=20 (one intersection point) y=-3 (one intersection point) This is what I got? y=2 (three intersection point) y=-40 (one intersection point) y=-1(three intersection point)
I did not get 4 anywhere.
we are not able to get 4 intersection points, because your function is a polynomial of degree= 3, s, at maximum, we get three solutions
ok thank you the desmos calculator is really helpful
