    [Maximum mark: 4]

    On a hot summer afternoon, engineers study how heat distributes along a new metal alloy rod. Let ​T(x)​ be the temperature in °C at a point ​x​  cm from one end of the rod, where ​0≤x≤2. The temperature gradient satisfies

    ​
    dxdT​=6x
    ​

    and it is observed ​T(2)=10.

    1. Find ​T(x).
