13. Use the mapping shown above to show the value of the function ƒ(x) at each point.

B

Step-by-step explanation:

Follow the arrow from the x- value in the domain to the corresponding value in the range, that is

x = - 1 → f(- 1) = 5

x = 0 → f(0) = 3

x = 1 → f(1) = 5

x = 2 → f(2) = 11

x = 3 → f(3) = 21

Thus B shows the appropriate mapping

0 is its x and y coordinate
