The function f(x) = 2·5x can be used to represent the curve through the points (1, 10), (2, 50), and (3, 250). What is the multiplicative rate of change of the function? (FAST) A. 2 B. 5 C. 10 D. 32 |

Answer» -step explanation:The MRC (multiplicative rate of change) can be solved USING this formula:MRC = f(X2)/f(x1) / (x2 - x1)If we use the COORDINATES (1,10) and (2,50),MRC = 50/10 / (2-1) = 5If we use the coordinates (2,50 and (3,250)MRC = 250/50 / (3-2) = 5The MRC will be the same SINCE the function is an exponential function. |
