If (-2, y) lies on the graph of #y = 4^x#, then what is y? Precalculus Exponential and Logistic Functions Exponential and Logistic Graphs 1 Answer mason m Jan 2, 2016 #y=1/16# Explanation: #(-2,y)# is found through plugging in #-2# for #x#. #y=4^-2# To find #4^-2#, move the negative exponent to the denominator. #y=1/4^2# #y=1/16# Answer link Related questions What is an exponential function?
