The temperature, f(t) of a cup of coffee after f minutes can be determined by the equation f(t) = 54(0.85). A graph of the function f(t) is shown below. If(t) 50 40- 30- 20 10- 5 10 15 20 Estimate the temperature after 15 minutesAn exponential model y = a . b passes through the points (0, 11) and (2, 176). What are the values of a and b? 0 = and b =Find the exponential equation whose graph passes through the points (-2, 16 and (1,12) y Preview
