Practice problem
Let f(x)=sin(x)f(x) = \sin(x)f(x)=sin(x) and g(x)=x2+π.g(x) = x^2 + \pi.g(x)=x2+π. What is f(g(x))?f(g(x))?f(g(x))?
sin(x+π)\sin(x + \pi)sin(x+π)
sin2(x)+π\sin^2(x) + \pisin2(x)+π
sin(x2+π)\sin(x^2 + \pi)sin(x2+π)
sin2(x+π)\sin^2(x + \pi)sin2(x+π)
sin(x2)+π\sin(x^2) + \pisin(x2)+π
Type a concept, like “slope” or “photosynthesis”.
