(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​

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
