Answer:

The Answer is C:  2  -3/200

Step-by-step explanation:

Hope this Helps :)

The ordered pair that is on g(x) is (2, -3/400)

How to determine the ordered pair?

The complete question is in the attached image

The function is given as:

[tex]f(x) = \frac 34(10)^{-x}[/tex]

The rule of reflection across the x-axis is:

g(x) = -f(x)

So, we have:

[tex]g(x) = -\frac 34(10)^{-x}[/tex]

Set x = 2.

So, we have:

[tex]g(2) = -\frac 34(10)^{-2}[/tex]

Evaluate the exponent

[tex]g(2) = -\frac 34 * \frac 1{100}[/tex]

Evaluate the product

[tex]g(2) = -\frac 3{400}[/tex]

This means that:

(x, y) = (2, -3/400)

Hence, the ordered pair that is on g(x) is (2, -3/400)
