Chapter 4, Problem 55RE

Electrical Engineering For the given functions f x x^3 +2x^8 and g x = x^3, a) Determine with justification whether f x = 0 g(x) is true. b) Determine with justification whether g x = 0 f(x) is true.

Determine whether the function is not differentiable using differentiability and continuity, and show the complete solution, thank you so much

1 + x In Exercises 47-48, let f(x) =- 1 - x 1 47. Find and simplify. x + 3 1 48. Find and simplify. x -6,
