Answer:
1. Option c
2. Option d
Step-by-step explanation:
This type of survey is includes a sample made up of voluntary responses. People only choose to or do not choose to respond.
This type of sampling method is most of the time unbelievable because generally only people with strong opinions about this particular questions will respond and it is usually towards the same direction as the question and this might not reflect the opinion of the whole population making the survey biased.
2 + y= -3
subtract 2 from both sides
y= -5
Check:
2 + -5= -3
-3= -3
Hope this helps! :)
Answer: y=x³+2 or f⁻¹(x)=x³+2
Step-by-step explanation:
To find the inverse of the radical function, we replace y with x and x with y. Then, you solve for y.
![y=\sqrt[3]{x-2}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx-2%7D)
[replace y with x and x with y]
![x=\sqrt[3]{y-2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7By-2%7D)
[cube both sides to cancel out the cubed root]
[add both sides by 2]
Now that we have switched the variables and solved for y, we know that the inverse function is y=x³+2 or f⁻¹(x)=x³+2.
