To find the point of contact P (x1, y1) ...

To find the point of contact `P (x_1, y_1)` of a tangent to the graph of `y = f(x)` passing through origin O, we equate the slope of tangent to `y = f(x)` at P to the slope of OP. Hence we solve the equation `f' (x) = f(x_1)/x_1` to get `x_1` and `y_1`.Now answer the following questions (7 -9): The equation `|lnmx|= px` where m is a positive constant has a single root for

A

`plt(m)/(e)`

B

`0lt plt(m)/(e)`

C

`0lt p lt(e)/(m)`
