f(x) is greater than -10 because...      lim          x      →      −      ∞            3          x        ∗      3          −      8        −  10  =  0  ∗      3          −      8        −  10  =  −  10and the limit as x approaches infinity is infinityasymptote at -10(c)

3          x      −      8       can NEVER = 0as x becomes a smaller number,       3          x      −      8       approaches zero, but isalways a very small fraction above zeroif you plug in the equation in the calculator, it will saythat there is a value of exactly -10 because of round off error:the calculator will round if the answer is around-9.99999999999since y can&#039;t include -10, the answer is C

Use the graph of f(x)=3^(x-8)-10 to give the range of f(x). a) yle -10 b) y< 10 c) y>-10 d)y ge -10 e) y<-10 f) None of the above
