Question

Find domain and range.​

Answer 1

Answer:

2.

Domain: all real values of x

Range: f(x)》-4

3.

Domain: all real values except x = 0

Range: All real values except f(x) = 0

Step-by-step explanation:

2.

Domain: all real values of x

Range: f(x)》-4

Because this is a concave up quadratic with a minimum turning point at (0,-4)

3.

Domain: all real values except x = 0

Range: All real values except f(x) = 0

Since x is in the denominator, it can't be 0

For f(x) = 0, x has to be infinity
