# What is the domain of f(x) = x^2+2x-3+x+3.

### 3 Answers | Add Yours

The domain of a function f(x) is the set of values of x for which f(x) is real and defined.

For the function f(x) = x^2+2x-3+x+3 , any value of x gives a real value of f(x). As the value of f(x) is real and defined for all values of x, the domain is the set of real numbers.

**The domain of the function is the set of real numbers R.**

x^2+3x

Hi,

x= domain

y= Range.

f(x) = x^2+2x-3+x+3.

f(x) =x^2+3x

f(x) for x=0,1,2...(domain)

f(x)=o,4,10(range)
