## electrochika 4 years ago let f be a function defined for all real numbers x. If f'(x) =( the abs val of 4-x^2)/(x-2) then f is decreasing on what interval? a. (-infinity, 2) b. (-infinity, infinity) c. (-2, 4) d. (2, infinity)

this question is asking "for what values of x is $\frac{|4-x^2|}{x-2}$ negative

2. anonymous

it is negative on $(-\infty,2)$

Thanks!
