- 2. Let g(x)= {-1/5x + 2, x<0 -2, x=0 x+2, x>0. Does the lim g(x) x→0 exist? If yes, give its value. If not, why?arrow_forwardLet f(x) = (3x^2 + 16x − 12)/(x + 6). Find L such that lim x→−6 f(x) = L, and prove that the limit is correct by completing a δ − ε proof for the limit of the function.arrow_forwardFind limit, if it exists. If the limiting value is infinite indicated if its positive or negative a) lim where f(x)= 2x+9 if x is less than equal to 4 x->4+ x^3-6 if x is greater than 4arrow_forward
