Area = b*h
A= 7*3=21 cm square
Answer:
The function is odd because it is symmetric about the origin.
Step-by-step explanation:
we know that
A function f(x) is even when
f(x)=f(-x) ----> the function is symmetry about the y-axis
A function is odd when
-f(x)=f(-x) ---> the function is symmetry about the origin
In this problem we have
f(x)=-5x
<em>Verify if the function is even</em>
For x=1 ----> f(1)=-5(1)=-5
For x=-1 ---> f(-1)=-5(-1)=5
so
f(x) is not equal to f(-x)
therefore The function is not even
<em>Verify if the function is odd</em>
we have
f(1)=-5
f(-1)=5
so
-f(1) is equal to f(-1)
-f(x)=f(-x)
therefore
The function is odd because it is symmetric about the origin.
