Log, thus, is largely a function. To do away with the Log you decide on for an inverse function. think of of it as a million/4 and four being inverses of the different and so their product supplies a relentless that is a million. So, the inverse function I stated is Exp. So in A: Exp(Log(-2x+7) = Exp(Log(x+4)) you are able to take the Exp of the two aspects, meaning that the two aspects are nevertheless the same relative to a minimum of one yet another. which provides: -2x+7 = x+4 resolve for x as you often might. attempt understanding B. further and in case you have problems i will further exaplin this.
