12. (a) The domain is x 2. (See the solution for 11.(c)). (b) f 9 ( x ) 5 h Section 4.1 Exercises 1. Maximum at x 5 b , minimum at x 5 c 2 ; The Extreme Value Theorem applies because f is continuous on [ a , b ], so both the maximum and minimum exist. 2. Maximum at x 5 c , minimum at x 5 b ; The Extreme Value Theorem applies because f is continuous on [ a , b ], so both the maximum and minimum exist. 3. Maximum at x 5 c , no minimum; The Extreme Value Theorem does not apply, because the function is not defined on a closed interval. 4. No maximum, no minimum; The Extreme Value Theorem does not apply, because the function is not continuous or defined on a closed interval. 5. Maximum at x 5 c , minimum at x 5 a ; The Extreme Value Theorem does not apply, because the function is not continuous. 6. Maximum at x 5 a , minimum at x 5 c ; The Extreme Value Theorem does not apply since the function is not continuous. 7. Local minimum at ( 2 1, 0), local maximum at (1, 0) 8. Minima at ( 2 2, 0) and (2, 0), maximum at (0, 2) 9. Maximum at (0, 5) Note that there is no minimum since the endpoint (2, 0) is excluded from the graph.
