Question

Domain and range from the graph of a continuous functionThe entire graph of the function h is shown in the figure below.Write the domain and range of h using interval notation.

Answer 1

Given the graph of the function h

The domain is all the possible values of x that can be substituted into the function

As shown: x varies between -1(closed) and 4(opened)

So, Domain = [-1, 4)

The range is all the possible values of (h) that can the function take

As shown: h varies between -4(closed) and 5(closed)

So, the range = [-4, 5]

So, the answer will be:

Domain = [-1, 4)

Range = [-4, 5]
