Answer:
D is correct.
Step-by-step explanation:



x - 2 = 0 or x + 4 = 0
x = 2 or x = -4
So we have (2, -4) and (-4, 8). D is correct.
Answer:
The annual simple interest is 4.5%
Step-by-step explanation:
54/4= 13.5
13.5/300= 0.045
Fill in the point values in the formula for the derivative.
____
<u>Example</u>
y = x^2 + 3x . . . . . we want y' at (x, y) = (1, 4)
y' = 2x +3 . . . . . . . take the derivative dy/dx of the function
Fill in the value x=1 ...
y' = 2·1 +3 = 5
The value of the derivative at (x, y) = (1, 4) is 5.
