To find the inverse we have to first change the function notation to 'y'
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
Answer: natural numbers
Step-by-step explanation:
The answer i believe is 4000
Set this up as a proportion.
400/15 = x/6
Solve for x.
I just hope to help! :)
