Hence, (B) is not the correct choice from the given multiple choices of the function f that represents the vertical stretch by a factor of
Consider choice (C)
Since, the graph of
The equation
Hence, (C) is the correct choice from the given multiple choices of the function f that represents the vertical stretch by a factor of
Consider choice (D)
Since, the graph of
The equation
Hence, (D) is not the correct choice from the given multiple choices of the function f that represents the vertical stretch by a factor of
Consider choice (E)
Since, the graph of
