Answer:
f(x) is equal to -1 when x=3
Step-by-step explanation:
we have
This is a constant function
we know that
A <u>constant function</u> is a function whose output value is the same for every input value
therefore
when x=3 (input value)
The value of the function is y=-1 (output value)
The answer is A, 
. This is because when plugging in -2 for x, the expression will look like this: 
. To make the exponent positive, you have to flip it into a fraction. Then it will be 
. Lastly, you simplify the denominator into 81.
