Question
16. Find the inverse function of f.
f(x) = x² – 3, x 2 0
%3D
Then, use compositions of functions to verify the two functions are inverses of each
other.
. Use Hooke's Law, which states that the distance a spring stretches (or compresses)
from its natural, or equilibrium, length varies directly as the applied force on the
spring.
A force of 220 newtons stretches a spring 0.12 meter. What force stretches the
spring 2 meters? (Round your answer to two decimal places.)
Also, for further review, understand how to deal with "varies inversely" an
"varies jointly".
