Answer:
See Below.
Step-by-step explanation:
We want to show that the function:
Increases for all values of <em>x</em>.
A function is increasing whenever its derivative is positive.
So, find the derivative of our function:
![\displaystyle f'(x) = \frac{d}{dx}\left[e^x - e^{-x}\right]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20f%27%28x%29%20%3D%20%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%5Be%5Ex%20-%20e%5E%7B-x%7D%5Cright%5D)
Differentiate:
Simplify:
Since eˣ is always greater than zero and e⁻ˣ is also always greater than zero, f'(x) is always positive. Hence, the original function increases for all values of <em>x.</em>

Perimeter = 9 + 13 + 6 = 28 m
area = 1/2 x 9 x 5.3 = 23.85 square m
Answer:
No.
Step-by-step explanation:
We substitute the values x = 2 and y = -4 into the inequality.
Left side = 2(2) - 3(-4) = 4 + 12
= 16
Now the right side is 15 so we get 16 < 15 which is incorrect.
So (2, -4) is not a solution.
