Given the pts A (a, log a) and B (b, log b) on the curve y= log x, a is not equal to b.
(c) Given point Q is directly to the left of M on y = log x
(i) Find the coordinates of Q.
(ii) Show that x^2 with the base of Q = ab
For (i), I was wondering: For the y coordinate, I found it to be log ((a+b)/2). I was wondering how the answer becomes 1/2log ab (thatís what my teacher got). If itís wrong, could someone please show me how to simplify it?
For (ii), I have no clue how to solve the question. Could someone please guide me?
N.B. For all the logs in this question, they are in base 10. Sorry
