When strontium-90 decays, it transforms into yttrium-90, which has a half-life of only 64 hours, (0.007302 years). If the decay constant of yttrium-90 is −94.93, what percentage of a one-pound sample will be left after one month ( of a year)?

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
