Answer:
y= 3- x/3
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=9−3x so it becomes x=9−3y.
Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)
Answer:
y=(-x/3)+3
Step-by-step explanation:
y=-3x+9
x=-3y+9
x-9=-3y, next division
(x-9)/-3=y
simply and rearrange
y=(-x/3)+3
