Using the First Derivative Test, what are the local maximum/minimum for the following function? f (ac) = 3 CO N - 10x2 + 48x + 1 There is a local minimum at x=4 and a local maximum at x=6. There is a local maximum at x=4 and no local minimum. There is a local maximum at x=6 and no local minimum. There is a local maximum at x=4 and a local maximum at x=6. There is a local maximum at x=4 and a local minimum at x=6
