Question

Graph y=-2x. give the domain and range. is the function dicrete or continou?

Answer 1

Domain: (−∞,∞),x

Range: (−∞,∞),y∈R

Explanation:

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),x∈R

Range: (−∞,∞),y∈R
