Find the absolute minimum and maximum value of the function f(x) = 1/x+3
Question
Find the absolute minimum and maximum value of the function f(x) = 1/x+3
Solution
To find the absolute minimum and maximum values of the function f(x) = 1/(x+3), we first need to find the critical points of the function.
Step 1: Find the derivative of the function The derivative of f(x) = 1/(x+3) is f'(x) = -1/(x+3)^2.
Step 2: Set the derivative equal to zero and solve for x Setting f'(x) = 0 gives us -1/(x+3)^2 = 0. However, this equation has no solution because the expression -1/(x+3)^2 is never equal to zero for any real number x.
Step 3: Check the endpoints and critical points Since the function has no critical points, we only need to check the endpoints. However, the function f(x) = 1/(x+3) is defined for all real numbers, so it has no endpoints.
Therefore, the function f(x) = 1/(x+3) has no absolute minimum or maximum value. The function approaches 0 as x approaches positive or negative infinity, but it never actually reaches 0. Similarly, the function becomes arbitrarily large in magnitude as x approaches -3 from the left or the right, but it never actually reaches positive or negative infinity.
