and
since these equations both =y then set them equal to each other
so then solve for to get the values
thus
Hi everyone I have a maths question as follows:
Plot the graphs of y=x^2+x-1 and y=x+1 as accurately as possible on the same axis using value of x from -4 to +4
Write down an equation for the values of x where the graphs meet and solve this equation. Check and show the solution on the graph.
OK so I have drawn it by hand but to illustrate I plotted it in excel for you all to see here:
Can anyone tell me how to find out the equation I need to answer this question please?
Thanks for your time - James
