A. isn't correct because functions are by their definition different.

B is true. Domain of both is x>0 and range is 1/2 as large. because of 1/2 factor in first function

C is true . because of -2 it is shifted to the right by 2 and it is shrunk vertically by 1/2

D isn't true because ranges are not the same.

We know A is correct because the characteristic function involved is sqrt(x); the multiplying factors simply shrink and enlarge the graph. Therefore, A is true.
The first part of B is true; however, the second part about the ranges being different is incorrect. This is because the values of y, the range, can vary from zero to positive infinity.
The similarity stated in C is true and the (-2) within the square root serves to shift the graph to the right two units. Thus, C is correct.
D is also correct as both functions have the same domain and range, that is 0 to infinity for both domain and range in both cases.

The volume of water that goes into the hose is the same as the volume of water that comes out the nozzle. This means the velocity is inversely proportional to the area. The area is proportional to the square of the diameter.

Taken together, these facts mean that if the diameter is divided by a factor of 3, the velocity is multiplied by a factor of 3^2 = 9.

Nozzle velocity = 3^2 * entering velocity
.. = 9 * (4 m/s)
Nozzle velocity = 36 m/s . . . . . . . . . corresponding to selection A
