The answer for this question is 5/36
Answer:
f^-1(x) = x+1
Step-by-step explanation:
turn into y = x-1
1. Flip x to y and y to x
x = y-1
2. isolate y
x+1 = y
using a graph you can find it by reflecting x-1 over y=x
Already you can see that -y and y will make a zero
add both together
3x=21
x=7
plug x in
7+y=5
y=-2
The answer is b because 60% is not in the word problem, so you could've used process of elimination to get rid of choice a.
