What is the equation of the exponential graph shown?Please help :'(
Question
Answer:
The equation of the exponential graph is y = 100(0.5)^xHow to determine the exponential equation?On the graph, we have the following points(x,y) = (0,100) and (1,50)An exponential equation is represented as:y = ab^xWhere a = y, when x = 0.This means thata = 100So, we have:y = 100b^xAt the point (1,50), we have:50 = 100b^1Evaluate50 = 100bDivide both sides by 100b = 0.5Substitute b = 0.5 in y = 100b^xy = 100(0.5)^xHence, the equation of the exponential graph is y = 100(0.5)^xRead more about exponential equations at:
