The rate, R, of photosynthesis for a certain plant depends on the intensity of light,x, in lumens, according to: R(x)=270x-90x^2
Rewrite r(x) in vertex form by completing the square? What is the intensity x that gives the maximum rate,R, of photosynthesis? What is the maximum rate, R, of photosynthesis?
