Company XYZ know that replacement times for the quartz time pieces it produces are normally distributed with a mean of 15.5 years and a standard deviation of 2.4 years. Find the probability that a randomly selected quartz time piece will have a replacement time less than 8.5 years

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
