How do i find all the rational zeros in f(x)= 9x^4-9x^3-58x^2+4x+24

Determine the fraction of total interest owed. after the fourth month of a 12-month loan: the numerator is: {(n + ) + (n + ) + (n + ) + (n + )} = , and the denominator is: {(n) + (n + 1) + + (n + )} = . therefore, the fraction is numerator/denominator (to the nearest tenth) =

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?
