The parent function of the image is,
![y=(1)/(2)x^2](https://img.qammunity.org/2023/formulas/mathematics/college/7nwr0zzwgyh46s7cj5bmvazbd5hslhqb1i.png)
The transformation of the graph will be
1) It was reflected, which then changes the function into
![y=-(1)/(2)x^2](https://img.qammunity.org/2023/formulas/mathematics/college/1xrmjk70xqt070veylcorzrp8x101mrzgb.png)
2) After that, it was shifted to the right horizontally by 3units. The result now turns into
![y=-(1)/(2)(x-3)^2](https://img.qammunity.org/2023/formulas/mathematics/college/qpb692zem9y7lc1rebk6dgfnseklwing3g.png)
3) Finally, it was shifted vertically upward by 5units. The resulted function is now
![y=-(1)/(2)(x-3)^2+5](https://img.qammunity.org/2023/formulas/mathematics/college/qshb0xdctnadziir16olmxddys3y1ath0i.png)
Hence, the function of the graph is
![y=-(1)/(2)(x-3)^2+5](https://img.qammunity.org/2023/formulas/mathematics/college/qshb0xdctnadziir16olmxddys3y1ath0i.png)
The correct option is Option C.
