Identify the domain of the function shown in the graph.

Leno4ka [110]

Domain is set of all x-values. You are supposed to focus on the x-axis instead.

From the graph, the point starts from x = -5 and ends on x = 5. That means no values would exist after x = 5 or before x = -5.

Hence, the domain starts from -5 to 5.

Answer

-5≤x≤5

One electrician charges his customers a $60 service fee plus $35 per hour.

gavmur [86]

Answer:

2 hours; $130

Step-by-step explanation:

We can do this by setting up an equality since we are finding when they are the same. Say x is the number of horus:

65 * x = 60 + 35* x

30 * x = 60

x = 2 hours

The cost will be the same at two hours, and plugging it in, we can get 65*2=130.
