If y = 4x - 5 is a tangent to the curve y2 = px3 + q at (2, 3), then
p = 2, q = - 7
p = - 2, q = 7
p = - 2, q = - 7
p = 2, q = 7
The greatest value of f(x) = (x + 1)1/3 - (x - 1)1/3 on [0, 1] is
1
2
3
B.
2
Clearly, f'(x) 0 for any other value of x [0, 1]. The value of f(x) at x = 0 is 2.
Hence, the greatest value of f(x) is 2.
