Given information
Here, Suppose the graph of is given, have to write equations for the graphs that are obtained from the graph of as, stretch vertically by a factor of .
Step-by-step explanation
Step 1.
Consider the stretching if, then the graph of is the graph of stretched by a factor of in the vertical direction (because each -coordinate is multiplied by the same number ).
Therefore, the function is stretched vertically by the factor of , thus the required equation is:
.
