In Problems 7–18, match each graph to one of the following functions:
The given graph is matched to the function
There is the given graph we have to match each graph to its functions.
The given graph is similar to the function of the graph but it is vertically stretched by a factor of .
When the right side of a function is multiplied by a positive number a, the graph of the new function is obtained by multiplying each y-coordinate on the graph of by a. The new graph is a vertically stretched version of the graph of
Since the given graph is vertically stretched by factor of
The function of the given graph is role="math" localid="1645865928495" that matched to option K.
