5-3-3 Drawing a Graph u To store an X = constant expression *1 Example To store the following expression in memory area X4 : X = 3 3(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. u To store an inequality *1 Example To store the following inequality in memory area Y5 : y > x2 - 2x - 6 3(TYPE)6(g)1(Y>) (Specifies an inequality.) vx-cv-g(Inputs expression.) w(Stores expression.) u To create a composite function Example To use relations in Y1 and Y2 to create composite functions for Y3 and Y4 Y1= (X + 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 м -1)) Input relations into Y3 and Y4. 3(TYPE)1(Y=)J4(GRPH) 1(Y)b(1(Y)c)w J4(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. 200509401
