Answer:
3, in both a), b)
Step-by-step explanation:
a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.
Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is . In particular, the value we are looking for is
.
If you would like to compute the equation of the tangent line, we can use the point-slope equation to get
b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to .

Doing what the directions say is generally a good idea.
Adding a number moves to the right; subtracting a number moves to the left. Subtracting a negative number is the same as adding its opposite.
The arrowhead end of the line in the figure is the end result. Two of them end up to the right of -8, that is, greater than -8.
