Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
It took 9 hours of labor. 500 - 140 = 360...... 360 / 40 = 9.
Answer: 9.

Answer: y = -1x + 2</h2>
Step-by-step explanation:
Points ( -3,5 )( 6,-4 )
You use the slope formula to find the slope.
<h3>Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.</h3>
M = Y2 - Y1 over
X2 - X1
Which is -4 - 5
6 - -3 = -9/9 = -1
The slope is -1
Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )
And plug them in
-4 = -1(6) + b
-4 = -6 + b
+6 +6
2 = b
The equation will be y = -1x + 2
