3n-3x-15 You have to add the like terms.
The domain for exponential functions will be all real numbers. Then the correct option is C.
<h3>What are domain and range?</h3>
The domain means all the possible values of x and the range means all the possible values of y.
The exponential function is given as,
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ + c
Where c is the addition constant.
The domain for exponential functions will be all real numbers.
And the range of the exponential functions will depend upon the equation.
Then the correct option is C.
