Which two functions are inverses of each other?
f(x) = x, g(x)=-x
f(x) = 2x, g(x) = -1/2x
f(x) = 4x, g(x) = 1/4x
f(x) = -8x, g(x) = 8x

Solve |2x - 5| = 4 if anyone could , that would be great

According to a study done by de anza students, the height for asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. suppose one asian adult male is randomly chosen. let x = height of the individual. a) give the distribution of x. x ~ b) find the probability that the person is between 64 and 69 inches. write the probability statement. what is the probability?

Given the functions, fx) = x^2-4 and g(x) = x+ 2, perform the indicated operation. when applicable, state the domain restriction. f(g(x))
