Rewrite as y = 2 / (x^2 + 2). Swap all x and y symbols to create x = 2 / (y^2 + 2). Rearrange for y to reach y=g(x)=sqrt( (2-2x) / x ).

This is an example of differentiation. With differentiation the key rule that allows us to differentiate most algebraic functions is "times the coefficient by the power then decrease the power by one...

El Niño cycles occur periodically, on average every 3- 7 years in the Pacific Ocean. Normally-descending air over the Eastern Pacific gives dry condi...

Firstly, ff(8) is the same as f(f(8)) so f(8) needs to be found first. Subbing in x=8 f(8)=22/3, so f(22/3) is required, Setting x=22/3 f(22/3)= 20/(22/3 - 5) = 60/7. so ff(8)=60/7.Next, as x tends to in...

Data is stored one a continuous spiraled track around the optical disk, the track is made up of a continuation of lands and pits, where lands will reflect the light focused onto them, and pits will scatte...
