Answer:
22
Step-by-step explanation:
Find f(-3) :
f(x) = x² + 2x for x ≤ -3
That means for those values of x, less than or equal to -3, this is the function.
So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3
Now, f(-1) :
From the given data, we see it is: f(x) = 2 
We take this because -1 lies between -3 and 4.
Now, f(-1) = 2 
=> 
For f(4) :
Clearly, the function is: 
Therefore, <u>f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.</u>
Here is you're answer:
In order to get you're answer you need to find the common denominator then add.
- Find the common denominator:
- Simplify:
-
Therefore you're answer is option D "13/24."
Hope this helps!
Temp1 = 60
Temp2 = 75
Temp2 - Temp1 = 15
Difference = (Temp2 - Temp1) / Temp1
Difference = 15 / 60 = 1 / 4 = 0.25
Percentage difference = difference * 100% = 0.25 * 100% = 25%
The cost never decreases as it is always going up based upon your x-value and your degree. Mark me as brainliest please.
