Ifound out that the max value is 3 but how do i find the equations of the tangents?
find the maximum value of 4x - x - 1
and sketch the curve y = 4x – x² – 1
for 0 < /= x < /= 4. determine the
equations of the tangents to the curve
at the points whose x-coordinates are
1 and 3. show that these tangents
intersect at the point (2, 4). calculate
the area of the region bounded by
the curve and the two tangents.
