Question

Please hurry!

Here is the graph of a function showing the amount of money remaining on a subway fare card as a function of the number of rides taken.

What is the output of the function when the input is 10? ____

What is the input to the function when the output is 5? _____

Answer 1

10 is 14 (10,14) and 5 is 16 (5,16)

Explanation:

the output is the same as the x value or the number of rides taken. The y is the amount on the card, or how much money is left of the card. So to solve this question, you want to follow the x-axis (the bottom numbers) til you reach the output you need then match that with the input by looking directly left on the chart. Hopes this helps!
