Could someone show me how to do a,b?

YOU. Glapil Sketching. TOl each Of THE TOHOWIng TUL 1 + 2 2 (a) f(2) = 1 - 2 2 ( b ) f ( 20 ) = x2 + 1 1 ( d) ( * ) f (2 ) = el/z (e) f(a) = 2 2 - 1 Determine where possible . domain of f . asymptotes of f. . x and y intercepts of the graph y = f(x) . local extrema of f . intervals over which f is increasing . intervals over which f is decreasing . intervals over which f is concave up . intervals over which f is concave down . points of inflection of f Use these results to sketch the graph of y = f(x). Hint for (d): Consider left and right limits as x approach
