Answer:
slope = - 1
Step-by-step explanation:
The slope of the curve m is measured by
m = 
at x = a
Differentiate using the power rule
(a
) = na
Given
y = - 3x - x², then
= - 3 - 2x
x = - 1 → = - 3 - 2(- 1) = - 3 + 2 = - 1 ← slope at (- 1, 2 )
Step-by-step explanation:

Answer:
x^2-2x-4=0
Δ=2^2-4*1*(-4)
Δ=4+16=20
VΔ=2V5
x1= (2+2V5)/2=1+V5
the answer is D
Step-by-step explanation:
Answer:
- 64
Step-by-step explanation:
