1. The problem statement, all variables and given/known data h(x)=(5-5x2)f(x) h'(x)=6xf(x)+4x4+2x2 2. Relevant equations Find f(x) 3. The attempt at a solution I tried finding h'(x) from the first part and then equating the two, but this does not seem to work. Urgent help required TEST in 2 hours! The general method may be provided does not have to solve this exact question as the values may not be 100% i am recalling from a person who has already written the test so the general method is required.
