<span>A 90 degrees counterclockwise rotation about the origin followed by a translation 1 unit to the left</span>
Answer:
Option D
Step-by-step explanation:
Given f(x) = ![\sqrt[3]{4x}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4x%7D)
g(x) = 2x + 3
Since, 
![=\frac{\sqrt[3]{4x}}{2x+3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B4x%7D%7D%7B2x%2B3%7D)
This function is defined for the denominator is not equal to zero.
(2x + 3) ≠ 0
x ≠ 
Therefore, Option D will be the correct option.
Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640
Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14
Sales income
<span>Average ticket $ 36 .40
</span><span>Break-even point = <u> (fixed costs) </u>
(income per passenger – costs per passenger) </span><span>
</span>
Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
