The graph of the function decreases from left to right.
Option C is correct.
Step-by-step explanation:
We are given the function:
and we need to fill the table
if x = -3 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = -2 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = 2 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
if x = 3 then y=?
Putting value of x in the given function:
Applying exponent rule a^-b= 1/a^b
So, x=-3 then y= 27
x= -2 then y= 9
x=2 then y:
x=3 then y:
Graph of the function is shown in figure attached.
The graph of the function decreases from left to right.
Option C is correct.
