For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in

Shalnov [3]

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 $p'(x)=3x^2-9$ . In particular, the value we are looking for is $p'(2)=3(2^2)-9=12-9=3$ .

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get $y=3(x-2)-10=3x-16$

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 $p'(2)=3$ .

What 2 numbers add up to get 17 and multiply to get -200

alexira [117]

There is no fixed equation when I arrived at these numbers.

I just did trial and error. I came up with 25 and -8 as the numbers.

200 ÷ 25 = 8 ⇒ the sum of 17 depends on the signs of each numbers.

-8 x 25 = -200

-8 + 25 = 17
