Answer:

  • C) Decay; (0, 4)

======================

Given function:

  • f(x) = 4 × (1/3)ˣ

This is an exponential function with the base of 1/3, which is between 0 and 1, hence its value reduces with greater power. So it is an exponential decay.

The y-intercept is the value of the function at x = 0:

  • f(0) = 4 × (1/3)⁰ = 4 × 1 = 4

Correct answer choice is C.
