Which function represents a reflection of ƒ (x) = 2x?

h (x) = 2^x + 1

h (x) = 2^x - 1

h (x) = 2^x - 1

h (x) = 2^-x

A reflection across the x axis means times the whole thing by - 1

reflect across y axis means multiply every x by - 1

so we got

from f (x) = 2x

a reflection across either axis results in f (x) = - 2x

but wat

why we have exponents

I pick the last option, h (x) = 2^-x
