Answer: ![f^{-1}(x)=2x-6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D2x-6)
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[switch x and y]
[subtract both sides by 3]
[multiply both sides by 2]
![y=2x-6](https://tex.z-dn.net/?f=y%3D2x-6)
Now, we know that
.
Answer:
We can't solve this because we can't add graphs. One way you could solve it would using Desmos.

Answer:
40πcm
Step-by-step explanation:
circ = 2πr
if d = 40cm
r = 20cm
∴ c = 2×π×20
= 40πcm
= 125.66cm
The answer is 1. I got this by dividing 118 by 9 and the 9 times 13 which equals 117. 117+1= 118
