The mean= 5.5
The median= 6
The range= 10
The IQR= 5
I really hope this helps:)
(f+g)(x)=f(x)+g(x)
=3x-2+2x+1
=5x-1
To find the vertex it the h and k.
For ex: 4(x+5) 7
Ur h is - 5 and ur k is 7
So the vertex is (-5,7)
Also u take the opposite what in the parenthesis, since it positive 5, it becames - 5.
