Answer:
ion
Step-by-step explanation:
Find the inverse, interchange the variables to solve for y
f-1 (x)=-
![\frac{8- \sqrt[]{_2(-8+x)} }{2} ,](https://tex.z-dn.net/?f=%20%5Cfrac%7B8-%20%5Csqrt%5B%5D%7B_2%28-8%2Bx%29%7D%20%7D%7B2%7D%20%2C)
Answer:
7 hours
Step-by-step explanation:
First you subtract 20 from 69, as the starting fee. That leaves you with 49. 49/7 = 7 hours
The Domain of a function is described as the set of all the x values that a function can take.These are the allowable values of a function.
From the table we can see that the first column shows the x values for the function. So the set of all values will be the Domain of the function.
Hence the Domain is {-2, -1, 0, 1}
So, option B gives the correct answer
You'd add both functions together:
(|x|+9)+(-6)
So:
|x|+3
