The question says that the y-coordinate of the y-intercept of the graph of the function must be either a base or coefficient of the answer, so we should solve for that y value first. To get the y-coordinate of the y-intercept, we must set x equal to zero. Setting x to 0 will leave us with the function f(x) (which just represents y) equals 3-2. 3-2 equals 1/9, (this can be done with a calculator), and answer choice B is the only choice that has 1/9 as a coefficient or base, so B is the answer.
