Give me a function problem

Solution

Here’s a function problem for you:

Problem:

Let f(x)=2x33x2+4x5f(x) = 2x^3 - 3x^2 + 4x - 5.

  1. Find the value of f(2)f(2).
  2. Determine the first derivative, f(x)f'(x).
  3. Find the critical points of f(x)f(x).
  4. Determine the intervals where f(x)f(x) is increasing or decreasing.
  5. Find the local minima and maxima of f(x)f(x).
  6. Compute the second derivative, f(x)f''(x).
  7. Determine the concavity of the function and find any inflection points.
  8. Calculate the y-intercept and find the roots of f(x)f(x) (if any).

Would you like details on how to solve any of these parts, or do you have any questions?
