Answer: 2,5

Explanation:

In order to find the domain of a function, check the function for two conditions:

a zero in a denominator

a negative under an even root

Exclude the values at which the function satisfies either or both of these conditions from its domain.

G(x) has no root but it does have a denominator. Therefore, check the first condition by setting the denominator equal to zero and excluding those solutions from the domain.

x2 - 7x + 10 = 0

(x - 2)(x - 5) = 0

x = 2, 5
