What is the domain of y=3^x -2

All real numbers

Step-by-step explanation:

The given exponential function is

This function is obtained by shifting, the parent function down by 2 units.

The parent function is

The domain is the values of x for which the function is defined.

The exponential function is defined everywhere and the same applies to the transformed function.

Therefore the domain is all real numbers.

1/800 is the right answer

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
