Given transformation is f(x+5) which is similar to f(x+h).
f(x+h) shifts the graph "h" units to the left side.
so that means f(x+5) will shift the graph "5" units to the left side.
Left or right movement is done using x-coordinate only so -3 will change in (-3,7)
-3+5=2
so the new coordinate of the point will be (2,7)
Hence final answer is (2,7).
