Question 657769
As the problem states, you will need a graphing calculator (or program). Jujst enter the equation
{{{y=2x^4+(7/2)x^3-2}}}
And try to determine the integers between which the graph crosses the x-axis (where the zeros are). If your calculator/program has a trace function, then that can be very helpful.<br>
Here's what the graph looks like:
{{{graph(400, 400, -5, 5, -5, 5, 2x^4+(7/2)x^3-2)}}}
See if you can figure out the integers between which the graph crosses the x-axis.
