Question

Using g (2) = |2| + 3 find the following.
Calculate g(2) =
Calculate g(-2) =

Answer 1

g(2) = 5

g(-2) = 5

Explanation:

We are give g(2) = |2| + 3. We can find the function from this:

g(x) = |x| + 3

Absolute value turns any number positive:

g(-2) = |-2| + 3

g(-2) = 2 + 3

g(-2) = 5

g(2) = |2| + 3

g(2) = 2 + 3

g(2) = 5
