Given:
The graph of a function.
To find:
The zeros of this function on the graph.
Solution:
We know that, zeros are the values at which the values of the function is 0. It means, the points where the graph of function intersect the x-axis are know as zeros of the function.
From the given graph it is clear that, the graph intersect the x-axis at two points.
Therefore, the marked points on the below graph are the zeros of the function.
Answer:
1
Step-by-step explanation:
We are given that

Numbers are in radians
Substitute x=-1

Substitute x=-0.25

Substitute x=-0.01

Substitute x=-0.005

Substitute x=0.005

Substitute x=0.01

Substitute x=0.25

Substitute x=1

Therefore, 
M=(y₂-y₁)/(x₂-x₁). Let Z be the missing coordinate
3/5 = (Z - 2)/(8-3)
3/5 = (Z-2)/5
3 = Z-2 and Z =5, So Q(8,5)
A (-3, -1)
You know this because QIII is in the bottom left corner and both numbers are negative
