Answer:

vertical stretch of 3, horizontal compression to a period of π/5, phase shift of π units to the right

Explanation:

The parent function f(x) = cos(x) has been transformed to ...

y = A·f((2π/B)(x -C))

where A = 3, B = π/5, C = π

In this form, A is the vertical stretch factor, B is the period, and C is the right shift.

The function has been ...

vertically stretched by a factor of 3
horizontally compressed to a period of π/5
right shifted by π

This collection of transformations matches the 2nd choice in this list.
