Those lines on both sides of the number means "absolute value." Those lines tell us that the number is positive no matter what. So:

15 + |-3| - 4 → 15 + 3 - 4

Remember to follow PEMDAS when solving.

(15 + 3) - 4

18 - 4

Therefore, the answer is 14.

Best of Luck!

Answer: 14

Step-by-step explanation: The vertical bars around the -3 mean that we take the absolute value of that number which is the positive version of that number.

So the absolute value of -3 would be 3.

So we have 15 + (3) - 4 which simplifies to 18 - 4 or 14.

Notice that I used parentheses when first getting rid of the absolute value signs. I think that this method will help you avoid confusion when simplifying absolute values.

It's a good habit to get into for future problems.

The graph shows two functions, f(x) and g(x).

The graph shows two functions, f(x) and g(x). So point (-2,2) is on h(x)

<h3>What is graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

In the question, we have two functions f(x)=x²-2 and g(x)=x²+2 by adding the function we will get the combined function.

So the graph i attached is showing the two functions and their relation to each other.

So we can see from the graph that the function is varying from the coordinates (-2,2)

Hence graph shows two functions, f(x) and g(x). So point (-2,2) is on h(x)
