Original: y = 3^x
---To find the inverse, switch the x and y, then solve for y.
Inverse: x = 3^y
---Take the log base 3 of both sides to get y by itself
Answer: ![log_{3}(x) = y](https://tex.z-dn.net/?f=log_%7B3%7D%28x%29%20%3D%20y)
![y = log_{3}(x)](https://tex.z-dn.net/?f=y%20%3D%20log_%7B3%7D%28x%29)
Hope this helps!
Answer:
track expenses and items by costumer
Answer:
Step-by-step explanation:
Answer:
1.) y = 1.10(x – 1) + 1.35
Step-by-step explanation:
When x pounds of apples are purchased, the number of "additional" pounds is (x-1). The cost of those additional pounds is then added to the cost of the first pound to get ...
y = 1.10(x -1) +1.35
_____
<em>Comment on the function rule</em>
Personally, I think it is easier to write the rule as y = 1.10x +0.25, considering the first pound to have a $0.25 premium added to its otherwise $1.10 cost. This saves an operation when evaluating the formula for some value of x.
