The function C(t)=0.02(t-1948)^2+5sin(5.5t)+315 models the rise in CO2 levels when the earth reaches the critical concentration (C) of 450ppm, what year will it be? need to know the steps, not just answer

its a question from my assignment it comes with a graph but the graph doesnt go up to 450 ppm so i guess i'll just use a graphing calculator thanks
