H-E-L-P Determine the extrema of below on the given interval f(x)=5x^3-61x^2+16x+3 (a) on [0,4] The minimum is and the maximum is . (b) on [-9,9] The minimum is and the maximum is
(a) and (b) look the same to me. Maximum at x=-2/15; f(-2/15)= 3.272592592592593 Minimum at the beginning of the interval f(-2)=-85
Find the critical points in the intervals. The extrema is located at one of the critical points or at the boundary of the interval. Compare these values and pick the largest.
thats for the [0,4] interval?
can someone please show me the correct answer for this problem? its saying that one of them is wrong.
