Which graph represents a reflection of f(x) = one-tenth(10)x across the y-axis?

on a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and decreases into quadrant 4. it goes through (1, negative 1).
on a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in quadrant 1. it goes through (negative 1, 1).
on a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. it goes through (1, 1).
on a coordinate plane, an exponential function increases from quadrant 3 to quadrant 4 and approaches y = 0. it goes through (negative 1, negative 1).
