Find the domain of the function. a. f(x) = 2 − x x + 3 b. f(x) = x 2 + 3 x+ 4 x 2 + 1

(a)

To determine

To find: The domain of the function.

Explanation

Given information:

The given function is f(x)=2xx+3 .

Calculation:

The given function is,

f(x)=2xx+3 (1)

The numerator of the function is 2x .

The square root of a negative number is a complex number.

For the domain to be a real number, the value of 2x should be equal to and greater or 0

(b)

To determine
