Write the given function as the composition of two functions.y = -√/15+6xChoose the correct answer below.A. If f(x) = -√x and g(x) = 15 + 6x, then y = f(g(x)].XOB. If f(x)=√x and g(x)=O c. If f(x) = -D. If f(x) =1115+ 6x'13³√xthen y = f[g(x)].and g(x) = 15+ 6x, then y = f[g(x)].and g(x)= 15+ 6x, then y = f[g(x)]....
