Which function below is the inverse of f(x)= 7x-1/2
Keith_Richards [23]

Answer: f^{-1}(x)=\frac{x}{7}+\frac{1}{14}

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore, f^{-1}(x)=\frac{x}{7}+\frac{1}{14}.

Hope that helped,

If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume
Ann [662]
We're literally just comparing 200 to 800 here.
800 is 4× bigger than 200, of course.
To put that in a percent...
Well, 1 = 100%. (it's a whole)
So 4 = 400%
