Hi I am doing an online quiz for myself to get my math better for school and I have this question. I know the answer and how to get it however i am not sure how to write it.

the question is:

consider the function f(x) = (7x -7)^2 +1

the domain of f is:{x:__ <x<__}

the range of f is: {x:__<x<__}

i know that the domain would be all real numbers

and the domain is greater or equal to 1 but how do i answer that?

many thanks!!
