Question

Graph f(x) = x2 + 2 and state the domain and range of f

Answer 1

Answer:

Domain: all real value

Range: $f(x)\geq 2$

Step-by-step explanation:

Domain:

For all x belong to R:

There exist f(x)=x^2+2 such that f(x) belong to R

Range:

For all x belong to R:

$x^{2} \geq 0\\x^{2} +2\geq 2\\f(x)\geq 0$
