What is the domain of the function?​

{-2, 0, 4}

Step-by-step explanation:

Domain is defined as all the inputs possible to a function.

On a graph, you may know this as the value of x.

This means the domain is equal to all values of x that produce an output.

The only values of x that have a point on them is x = 4, x = 0, and x = -2, all of which have points on the x-value.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

note: the best i know.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
