Which ordered pairs lie on the graph of the exponential function f (x) = 3(0.2)^x
photoshop1234 [79]

The ordered pairs which lie on the graph of the exponential function, f(x) = 3(0.2)^x is; Choice A; (0, 3).

<h3>Ordered pair Solution;</h3>

The given exponential function is;

  • f (x) = 3(0.2)^x

By testing all values; Only the pair; (0, 3) is a solution to the graph of the exponential given.

By testing;

  • f (0) = 3(0.2)⁰.

  • Where, (0.2)⁰ = 1 (from indices).

  • f(0) = 3 × 1 = 3.
