- Does the graph below represent a function? How do you know? please answer!

Answer:
No, the graph does not represent a function because it does not pass the vertical line test.
<h2>What is a function?</h2>A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.
<h3>Vertical Line Test</h3>To pass the test, any vertical line that we draw on the graph should only touch one point.
A vertical line is a straight line that goes from top to bottom.
- Draw vertical lines through points on the graph, like in the photo below.
- Check if any vertical lines touch more than one point.
The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.

Answer:
70√2 units²
Step-by-step explanation:
(see attached for reference notes on parallelograms)
we are given ABCD is a parallelogram where
Short Length, AB = 10 units
Long Length, BC = 14 units
Angle A = 45°
The area of the parallelogram is hence,
= AB x BC sin 45°
= 10 x 14 x sin 45
= 140 sin 45° (recall from special angles, that sin 45° = 1/√2)
= 140/√2 (remove radical from denominator by multiplying by √2/√2)
= (140/√2) x (√2/√2)
=70√2 units²
The average rate of change of a function in the interval
is defined as
So, in your case, we have
