(a)The graph of the function : f(x) = x3 + x2 - 6x is shown below : (a) Use the "alternate” definition of the derivative to determine the formula for f'(x). y=x(x-2)(x + 3)
(b)Use your result in part (a) to compute the slope of tangent line to the curve at each x-intercept. Sketch the tangent lines on the graph and label each mtan​

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

it has changed from the width and the height.
