Answer:
The required function is
.
Explanation:
The given function is

The general equation is

Where, a represents the horizontal shift and b represents the vertical shift.
→ If a>0, then the graph of f(x) shifts left by a units and if a<0, then the graph of f(x) shifts right by a units.
→If b>0, then the graph of f(x) shifts upward by b units and if b<0, then the graph of f(x) shifts downward by b units.
Since the graph of f(x) shifted two units down and one unit to the left, therefore the value of b is -2 and the value of a is 1.

![[\because f(x)=x^2]](https://img.qammunity.org/2018/formulas/mathematics/high-school/y0e0aujjf5924o4ngv6d8szs0xu3mz2lp4.png)
Therefore the required function is
