Ineed to know the values of x that are not in the domain of h.

x = - 7, + 7

Step-by-step explanation:

The denominator of h(x) cannot be zero as this would make h(x) undefined. Equating the denominator to zero and solving gives the values that x cannot be.

solve :

x² - 49 = 0 ⇒ (x - 7)(x + 7) = 0 ⇒ x = ± 7

The domain is valid for all x ∈ R , x ≠ - 7, + 7

b

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
