Answer:
The correct option is 1.
Step-by-step explanation:
The given parent function is
![y=\sqrt{x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%7D)
It is a radical parent function. Portieres of this function are
1. Domain=[0,∞)
2. Range=[0,∞)
3. Graph of this function is a single continuous increasing curve.
4. It Increases at decreasing rate.
In first graph the a continuous curve starts from (-4,-1), and increasing at decreasing rate. So, it is represents the graph of a radical function.
![y=\sqrt{x+4}-1](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx%2B4%7D-1)
Therefore graph 1 is an example of a function whose parent graph is of the form y = √x.
Second graph is a U-shaped curve, so it is the graph of a quadratic function.
Third graph is a rectangular hyperbola, so it represents a rational functions.
In fourth graph the function increasing at increasing rate, so it represents an exponential function.
Therefore the correct option is 1.
