What is the inverse of the given function? y = 3x 9
2 answers:
Answer:
Step-by-step explanation:
The given equation is y=3x+9.
To find the inverse of the function we switch x and y then solve for y .This will give us the inverse of the function.
Switching x and y in the given equation we have :
x=3y+9.
Adding 9 both sides :
x-9=3y.
With y term 3 is multiplied .Dividing both sides by 3 we have:

Answer: y-1=6(x+7)
Step-by-step explanation:
The formula for point-slope form is . Since we are given the point and slope, we can directly plug them in.
[distribute by -1]
Now, we know that the point-slope form is y-1=6(x+7).
