Drawing a Graph

uTo store an X = constant expression *1Example To store the following expression in memory area X4 : X = 33(TYPE)4(X=c) (Specifies X = constant expression.) d(Inputs expression.)

w(Stores expression.)

• Inputting X, Y, T, r, or θ for the constant in the above procedures causes an error.

uTo store an inequality *1Example To store the following inequality in memory area Y5 : y > x2 − 2x − 63(TYPE)6(g)1(Y>) (Specifies an inequality.)vx-cv-g(Inputs expression.)

w(Stores expression.)

uTo create a composite function

Example	To use relations in Y1 and Y2 to create composite functions for Y3
	and Y4
	Y1 =	+ 1),Y2 = X2 + 3
	Assign Y1°Y2 to Y3, and Y2°Y1 to Y4.
	(Y1°Y2 =	((x2 + 3) +1 ) = (x2 + 4) Y2°Y1 = ( (X + 1))2 + 3 = X + 4 (X > −1))

Input relations into Y3 and Y4.3(TYPE)1(Y=)J4(GRPH)1(Y)b(1(Y)c)wJ4(GRPH)1(Y)c(1(Y)b)w• A composite function can consist of up to five functions.

*1A function cannot be stored into a memory area that already contains a function of a different type from the one you are trying to store. Select a memory area that contains a

function that is the same type as the one you are storing, or delete the function in the memory area to which you are trying to store.
