Question

What is the range of function g?

Answer 1

Answer:

Option B

Step-by-step explanation:

Equation of the function is,

$g(x)=\sqrt{x-1}+2$

Parent function of the given function 'g' is,

$h(x)=\sqrt{x}$

By translating the parent function 'h' n=by 1 unit horizontally left and 2 units upwards we get the function 'g'.

That means function 'g' starts from a point (1, 2).

Range of the function 'g' will be all the values of y ≥ 2.

Option B is the answer.
