Answer: D) The relation R is a function because for each input there is exactly one output
There's not much else to say other than what choice D already does. Visually we can use the vertical line test to confirm if we have a function or not. If we can pass a single vertical line through more than one point on a curve, then the curve isn't a function. The graph is said to have failed the vertical line test. Otherwise, the relation passes the vertical line test and we have a function.

Answer:
(a) $26.37 (b) $17.58
Step-by-step explanation:
The original price of a beach chair = $43.95
Janelle bought the chair on sale at = 60% off
The discount price = 60% of 43.95
= 
= 0.60 × 43.95
= $26.37
(a) The amount of discount = $26.37
(b) The sale price = 43.95 - 26.37 = $17.58
The amount of discount was $26.37 and the final sale price was $17.58.
