The first expression is true because x+x+x+x= 4x. It is like addition but with a variable. The second isn’t true because 5x= x+x+x+x+x whereas x+5 is x plus five. Not 5x. Hope this helps.

The domain of the graph is the one in option A.

D: 0 ≤ x ≤ 12

<h3>What is the domain of the graph?</h3>

For a function f(x) = y, we define the domain as the set of the possible inputs that we can use in the function.

Here we have a graph, in the case of graphs, the inputs are represented on the horizontal axis.

If you look at the horizontal axis, you can see that the graph goes from x = 0 to x = 12.

Then the domain is [0, 12], or written as an inequality:

D : 0 ≤ x ≤ 12
