Find the slope of the curve y=-3x-x^2 at the point (-1,2)

Mathematics
1 answer:
Elodia [21]3 years ago
6 0

Answer:

slope = - 1

Step-by-step explanation:

The slope of the curve m is measured by

m = \frac{dy}{dx} at x = a

Differentiate using the power rule

\frac{d}{dx} (ax^{n} ) = nax^{n-1}

Given

y = - 3x - x², then

\frac{dy}{dx} = - 3 - 2x

x = - 1 → \frac{dy}{dx} = - 3 - 2(- 1) = - 3 + 2 = - 1 ← slope at (- 1, 2 )

Answer:

C > 17

Step-by-step explanation:

23 - C < 6  

-23        -23

-----------------

-C < -17

multiply both sides by -1

(-c) (-1) > (-17) (-1)

C > 17
