Best ResponseYou've already chosen the best response.0I tried to elem. the parameter and got lnx^2  12lnx +36 ?

Best ResponseYou've already chosen the best response.1why would we want to eliminate the parameter? just because it says so?

Best ResponseYou've already chosen the best response.0Hum. So what do I do to get the equation? I cant just plug in (1,36) for x and y because ln(1) is 0.

Best ResponseYou've already chosen the best response.1well, since y = (t6)^2, and t=ln(x) y = (ln(x)6)^2

Best ResponseYou've already chosen the best response.0Okie dokie. So just 12x+1+36? So y=12x+37?

Best ResponseYou've already chosen the best response.0Story of my life. How about 12x+12+36 or y=12x+48
