Question

find the domain and range of the function f(x)=(x-2)(x-2)+5

Answer 1

\[f(x) = x^2 - 4x +4 + 5\] simplifying further we get \[f(x) = x^2 - 4x + 9\] looking at the function, we see that it is parabolic due to the x^2. at the same time, your domain are the x values. in other words, \[D= x; where x \in R\]

Answer 2

domain is: {R}
