Answer: Given f ( x ) = 2x + 1 and g ( x ) = x2
+ 2x – 1 find ( f + g ) ( x ) and
( f + g ) ( 2 )
Solution
Step 1. Find ( f + g ) ( x )
Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;
( f + g ) ( x ) = ( 2x + 1 ) + (x2
+ 2x – 1 )
= 2x + 1 + x2
+ 2x – 1
= x
2
+ 4x
Step-by-step explanation:
Answer:
X=5
X=2
X=0
Its right i go to k12
a - 30.2
b - 271.8
60/4=15
60/3=20
9+6.45+2.4+8.15+4.2=30.2
30.2x9=271.8
The area of the shaded region is 21.45cm².
There is a discontinuity at x=1
