Please calculat this queation
ever hear of using actual math notation?
f(x) = √(x+2)
g(x) = x^2 + 1
(f◦g)(x) = f(g) = √(g+2) = √(x^2+1 + 2) = √(x^2+3)
(g◦f)(x) = g(f) = f^2 + 1 = x+2 + 1 = x+3
now do the others in like wise
f(x) = √(x+2)
g(x) = x^2 + 1
(f◦g)(x) = f(g) = √(g+2) = √(x^2+1 + 2) = √(x^2+3)
(g◦f)(x) = g(f) = f^2 + 1 = x+2 + 1 = x+3
now do the others in like wise
