I am so sorry but i am geniuenly so lost, like do i just go 5 up and then go to the right till i hit the graf thingy? is it just that? Cuz i would say a=7... but i aint sure. I have a hard time picturing it since we didnt go through it at class 🥲

ya

f^(-1)(5) = 7 is correct

but how do i solve the problem for b, when i dont reallt have a function to go from. Cause just by looking at it i would guess a solied 2 as the solution for b

[hearty lava]
