What real values of x are not in the domain of f(x) = 1/(abs(x^2 + 3x - 4) + abs(x^2 + 9x - 10))?
All x except x = 1 (the denominator would be = 0 at x = 1)
the domain is all x except x = 1 (the denominator would be = 0 at x = 1)
\(f(x) =\frac{ 1}{|x^2+3x-4|+ |x^2 + 9x - 10|}\\ f(x) =\frac{ 1}{|(x+4)(x-1)|+ |(x+10)(x-1)|}\\ x\ne 1 \)
