Ordinatesy = f(x) + g(x) can be graphed by first graphing y = f(x) and y = g(x)
separately and then adding their ordinates together.

3. (D) Addition & Subtraction of
Ordinatesy = f(x) + g(x) can be graphed by first graphing y = f(x) and y = g(x)

NOTE: First locate points on y = f(x) + g(x) corresponding to f(x)=0 and
g(x)=0, then plot further points by addition and subtraction of ordinates
and finally locate the position of stationary points.

15. (E) Multiplication of Functions
The graph of y = f(x). g(x) can be graphed by first graphing y = f(x) and
y= g(x) separately and then examining the sign of the product. Special
note needs to be made of points where f(x) = 0 or 1, or g(x) = 0 or 1.
NOTE: The regions on the number plane through which the graph must
pass should be shaded in as the first step.
