Which of the following is an odd function?
Inga [223]

Answer:

f(x)=-x

Step-by-step explanation:

An odd function is symmetric with respect to origin.

It has the property,

f( - a) =  - f(a)

The only function that is symmetric about the origin is:

f(x) =  - x

Now let's put x=-a, to get:

f( - a) =  -  - a = a

Also

f(a) =  - a

We can see that:

f( - a) =  - f(a) = a

Hi, can someone help me with this question?
Wewaii [24]

Answer:

hi

Step-by-step explanation:

firstly we must divide the shape like this

and the area of first rectangular is 27 m²( 9m × 3m)

then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)

the third rectangular's area is 10 m² ( we found it from 9-4)

Total is 27+48+10=85 m²

hope it helps

have a nice day
