the key number is what is log(1) ? if you don't know, what does your calculator say?
logs are confusing (for me, anyway) but log(1) means what exponent gives us 1? (we assume base 10) 10 to what power is 1? the factoid to remember is 10^0 = 1 the power is 0 log(1) means what power gives us 1. and the power is 0 log(1)=0
ah sorry, didn't get a notification that you replied.
assuming you know log(1)=0 we look for the x value of the graph where it crosses the x-axis (i.e. where y is zero) what x value is that ?
would it also be 0?
you have to look at the graph. put you finger on the x-axis and move your finger along the x-axis until you reach the curve. then read what x value you are at . can you do that ?
now we have to figure out how to change log(x) so that it is translated (slid over) from x=1 to x= -2 (because it should be at 0 at x=1, but we see it was moved so that it is at 0 when x=-2)
the "fast way" is to memorize: to slide a function f(x) to the *left* n steps, write f(x+n) to slide the function f(x) to the *right* n steps, write f(x-n)
i figured it out :) thanks!
what did you get ?
