the graph of f(x) shown below resembles the graph of G(x)= x^4, but it has been changed somewhat. which of the following could be the equation of f(x)

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0
