The inverse of the function f(x) = is
B.
Hence, the required inverse function is
The equation of the bisector of the acute angle between the lines 3x - 4y + 7 = 0 and 12x + 5y - 2 = 0 is
99x - 27y - 81 = 0
11x - 3y + 9 = 0
21x + 77y - 101 = 0
21x + 77y + 101 = 0
If 5x - 12y + 10 = 0 and 12y - 5x + 16 = 0 are two tangents to a circle, then the radius of the circle is
1

6
If the coefficient of rth and (r + 1)th terms in the expansion of (3 + 7x)29 are equal, then r equals
15
21
