You have several types of graphs Function graphs Y_1=f(x), Y1=3X^2-4, [X, T, Theta, n] key types X Polar graphs r=F(theta), r=r_o*ln(theta). [X, T, Theta, n] types Theta Parametric graphs X_1=f(T) and Y_1=g(T). [X.T, Theta, n] types T Examples: X_1= cos(T). Y_1= 2(1--sin(T)) Sequence graphs u_n+1= f(u_n), [X,T,Theta,n] types n

Here you are trying to find the intersection point between two curves. Since you could have drawn more than 2 curves, the calculator gives you the opportunity to choose the first curve using the arrow Up/ arrow down to select. Once the curves are chosen, the calculator wants to know where (in the world is Carmen Sandiego) is the intersection point. And no it is not asking you to give the position, just what are the leftmost (1st guess) and rightmost (2nd guess) limits of the interval where the intersection point is. You use the left arrow to go a bit to the left of the intersection point (which you see on the graph) and press ENTER. Then you do the same for the 2nd guess.

Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg.
