The graph is a transformation of one of the basic functions. find the equation that defines the function.

Step-by-step explanation:

Note that the graph shown is a transformation of the parent function

The main function cuts the x-axis at x = 0 and has no negative values of y. In addition, the main function is always growing.

Note that the function shown is decreasing and intercepts the y-axis at y = 5.

Therefore, the graph of the main function has been reflected on the x-axis and displaced 5 units upwards.

If we do y = f(x) then to reflect the main function on the  x-axis and move it upwards 5 units we make the following transformation

.

Then the graphed function is:
