The intensity, I, of light passing through water can be modelled by the equation I=10^1-0.13, where x is the depth of water in metres. Most aquatic plants require a light intensity of 4.2 units for strong growth. Determine the depth of water at which most aquatic plants receive the required light.
I need help. This assignment consisting of a bunch of questions is due tomorrow.
