Q4. Given: F(x) = x4 - 5x2 + 4 1) Find the domain. 2) Find the intercepts. 3) Find f'(x), and determine the critical numbers. 4) Use the First Derivative Test to determine whether the function is increasing and decreasing 5) Determine the extrema. 6) Find f(x), and determine the inflection points. 7) Use the second derivative test to study the concavity and write the intervals on which the concavity is up and down. 8) Sketch the function
