The answer is A.
Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the swimming pool after d days, the water evaporates 0.9 cm in height each day. If the pool water starts at 1200 cm hence:
h(d) = -0.9d + 1200
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200
