Answer 1

Answer:

(a) Domain: x > 4

(b) Range: y < -2

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted by function f(x).

We see that our x-values span from 4 to infinity. Since it is an open dot, we cannot include it in our domain:

(-4, ∞)

We also see that our y-values span from -2 to negative infinity. Since it is an open dot, we cannot include it in our range:

(-∞, -2)
