Answer:
f(y) = y(y - 4).
Step-by-step explanation:
The function has two x-intercepts of the function are (0,0) and (4,0).
X-intercept means that the y-value will be zero.
Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.
Hence, the function x = f(y) has two factors (y - 0) and (y - 4)
So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)
