Question

What does the transformation f(x)↦3f(x) do to the graph of f(x)?
stretches horizontally or vertically ?

Answer 1

Using translation concepts, it is found that the transformation f(x)↦3f(x) stretches vertically the graph of f(x) by 3 units.

• In the transformation f(x) -> 3f(x), the function f(x) is multiplied by 3.

• When a function is multiplied by a constant with absolute value greater than 1, it is stretched vertically.

• An horizontal stretch is represented by f(x) -> f(ax), which is not the case here.

Hence:

The transformation f(x)↦3f(x) stretches vertically the graph of f(x) by 3 units.
