Consider $$f\left(x\right)=x^2-1\ and\ g\left(x\right),$$ which is a linear function that passes through the points (0,5) and (-1,5). Which statement accurately compares the intervals over which each function is positive or negative? (ws#17)

f(x) is negative for x-values between -1 and 1, and g(x) is never negative.

f(x) and g(x) are both positive for all x-values

f(x) is positive for all x-values, and g(x) is only positive for x>0

f(x) is positive for x-values less than -1 or greater than 1, and g(x) is always negative.
