Complete the following steps to find the lcd and
write the sum of the numerators for the given
problem:
2/x^2-3x-4+3/x^2-6x+8
factor each denominator:
x² – 3x – 4 =
x2 - 6x + 8 =
the least common denominator is:
(x - 4)(x + )(x- )

The graph of f(x), shown below, resembles the graph of g(x) = x2, but it has been changed somewhat. which of the following could be the equation of f(x)?
