I found the answer key t your worksheet. If you need an explanatin ask in comments and I will get back ASAP.
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.
The answer is
X=10 or X= -4
Answer:
The question is kinda funny. I think the graph isn't correct cos a and b coordinate ain't right
answer for this question is 2 is to 4 is to6 is to 7
