swapPooltokenForWethBasedOnOutputWeth function.

[GaurangBharadava]

I am not understanding fully that what the function is doing.

function swapPoolTokenBasedOnOutputWeth(uint256 outputWeth) public {
        outputWeth = bound(outputWeth, 0, type(uint64).max);
        if(outputWeth >= weth.balanceOf(address(pool))) {
            return; 
        }
        uint256 poolTokenAmount = pool.getInputAmountBasedOnOutput(outputWeth, poolToken.balanceOf(address(pool)), weth.balanceOf(address(pool)));

        startingY = int256(weth.balanceOf(address(pool)));
        startingX = int256(poolToken.balanceOf(address(pool)));
        expectedDeltaY = int256(outputWeth);
        expectedDeltaX = int256(pool.getPoolTokensToDepositBasedOnWeth(poolTokenAmount));

    }

Like for what outputWeth stands for? an how we can use that to get pooltoken. Also in getInputAmountBasedOnOutput

function getInputAmountBasedOnOutput(
        uint256 outputAmount,
        uint256 inputReserves,
        uint256 outputReserves
    )
        public
        pure
        revertIfZero(outputAmount)
        revertIfZero(outputReserves)
        returns (uint256 inputAmount)
    {
        return
            ((inputReserves * outputAmount) * 10000) /
            ((outputReserves - outputAmount) * 997);
    }

what this arguments passed in function are stand for? not getting right thing.
