[@ericbinderya3228]

need functions ASAP. would be a lifesaver!! very helpful video though, so thank you

[@ericbinderya3228]

trig functions with graphs etc

[@nadu6073]

why can you not take LN of both sides for the 3 mark question of the last example

[@mcgrathematics]

I suppose you can, but there's not really much we can do with ln(a + b) in terms of simple algebra. Unless you're seeing something I'm not!

[@wasimvillidad3000]

For your consideration: f(x) = √(7 - 3x) and its inverse have three points of intersection, two of which, do not lie on the line y = x.

[@mcgrathematics]

That is both correct and fascinating. Never seen this before, thank you!
