given the table of values below, which of the following ordered pairs are found on the graph of the inverse function?
2 answers:
Answer:
Option A. is the correct option.
Step-by-step explanation:
As per table given in this question values of the function has been given as
f(x) = -3 for x = -2
We can rewrite the function as f(-2) = -3
As we know inverse of the function means
or inverse function g(-3) = -2
and the ordered pair for the inverse function will be (-3, -2)
Similarly other ordered pairs for the inverse function given will be
(3, -1), (9, 0), (15, 1), (21, 2)
Therefore, the ordered pairs will be (-3, -2), (3, -1), (9, 0), (15, 1), (21, 2)
Option A is the right option.

Answer:
The answer to your question is 90 dB
Step-by-step explanation:
Data
I = 10⁻³
I⁰ = 10⁻¹²
Formula
Loudness = 10log ()
Process
1.- To solve this problem, just substitute the values in the equation and do the operations.
2.- Substitution
Loudness = 10 log
3.- Simplify
Loudness = 10log (1 x 10⁹)
Loudness = 10(9)
Loudness = 90
