Answer:

the largest interval of x values where f(x) is increasing is (-1,1).

Explanation:


f(x)=-x^3+4x+3

the domain of f(x) is all real numbers.

As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .

Graphically we can also show this that for the x-values in (1,-1) function is increasing.
