1. The problem statement, all variables and given/known data 2 curves f(x) and g(x) don't intersect, find the range of values of m can be. 2. Relevant equations $$f(x)=3x^2 - 2$$ $$g(x) = mx-5$$ 3. The attempt at a solution Could I work out the 2 values for m that mean g(x) is a tangent to f(x) at some point and then the range will be between them? PS. I've already solved it via another approach but I was just wondering if this would work as it was my first initial idea on solving it.
