I need full solutions for this question, I do not understand it.

A student was trying to complete their practice work quickly and unfortunately spilled some white out on the question. Part of the function and interval were covered up by the spill. The question the student was asked to solve was "determine the x-value where the tangent line is parallel to the secant line over the interval defined". The student correctly determined the x-value was x = 2 and it was also known that the slope of the tangent was positive. The function is defined as f (x) = x3 x2+3. The interval is defined as -1 s x s What are possible values that could be under the spill? You may use Desmos but you must provide a screen shot of the Desmos screen you used to solve the problem and then connect how the Desmos screen was used to solve the problem. Please round any decimal values to 3 decimal places. You are not solving for all possible answers, rather, a possible set of values that COULD be under the spill
