Hello. I have been assigned a set of questions for homework and have not had any problems with them, up until the last question of the set!
The questions is..
The function r(x) = 1/(x + 3) is transformed by a translation of 3 units up and 5 units to the right. The transformed function passes through the point (x,7). The value of x to the nearest hundredth is ___
I can't seem to remember how to find out whether a a function passes through a specific point and was looking for some help.
Thanks very much.
Ok, yes that will give you the answer that you need. But I think you are probably supposed to be rewriting the equation in translated form. Take a look at the link below. It gives a good explanation for doing those. The way we did it will give you the same answer, but I think you teacher probably wants you to know how to write out the actual steps. It's actually a good way to understand how functions work.
