4. (12 Points) 6 Given f (x) = (2 - 3)2(2-5) x - a a. 2.5/8 o For what values of a, if any, does lim f(x) = 0% (not -oo)? Explain clearly and completely. For all the values different to x as if we have hex ) or hex) where x = a the limit of at x -a Would not exist. when does this occur ? b. 3.5/ 4 Determine for what values of a, if any, does lim f(x) equal a finite number? Explain your reasoning. lim fox ) equals a finite number for LA a = 14 x- at 8 - 7 2199 3 we can cancel the an deniomm
