Consider the function. f of x is equal to 2 and 1 half minus 3 and 1 third x What is the x -intercept of f inverse of x ?

The x-intercept of f⁻¹ occurs where f⁻¹(x) = 0. Applying f to both sides gives x = f(0), and the function’s value at 0 is 2½ − 3⅓(0) = 2½. So the x-intercept is (2½, 0), choice B.
