Question

Which function represents a reflection of f(x) = 3/8 (4)^x across the y-axis

Answer 1

g(x) = 3/8(4)^–x

Answer 2

the function that would represent a reflection of the function y = f(x) =
`(3)/(8) * 4^x` would be a function where x is negative, that is to say the required function which is a reflection across the y axis is given by

`y = f(x) = (3)/(8) * 4^(-x)`
