Is x = 15 a solution to the equation 8x − 8 = 120

no it is x=16

Step-by-step explanation:

A

B

Step-by-step explanation:

The domain is the span of x-values covered by the graph, while the range is the span of y-values covered by the graph.

From the graph, we can see that the x-values covered by the graph is infinite as it stretches infinitely in both directions. Thus, the domain of the graph is all real numbers.

In interval notation, this would be:

Also, from the graph, we can see that the y-values covered by it only goes up to a maximum of y=4. The rest is all values less than 4. The range is all numbers less than or equal to 4. Therefore, in interval notation, this is:

We use brackets because we include the 4 in our range.

Thus, the answer is A and B.
