The function f(x) = ax^3 -x^2 + bx -24 has three factors. two of these factors are x-2 and x+4. determine the values of a and b, then determine the other factor. (my nelson advanced functions grade 12 book chapter 3) : )

The long jump record, in feet, at a particular school can be modeled by f(x) = 19.6 + 2.5ln(x + 1) where x is the number of years since records began to be kept at the school. what is the record for the long jump 11 years after record started being kept? round your answer to the nearest tenth.

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)
