Please Show work where possible 1. Use the graph of fat right to evaluate the following: 42- a. lim f (x) x -+ 2 ' 1 -3 -2 -1 N 4 x b. lim f (x) c. lim f (x) 2. For f(x)= *-16t x_4 , try to evaluate by lim f (x)direct substitution. Then algebraically simplify the function and try again.Evaluate the limits algebraically. xAZ x_2 4. InnH 1)0 x 5. Use the graphs of f and g at right to evaluate the following limits. a. m[f(x)+g(x)] xH b. Iim[f(x)g(x)] rm
