Question

plzz help me to solve this question​

Answer 1

Step-by-step explanation:

if x = 1,

f(1) = ( 2(1) + 1 )³

(2+1)³ [ (a+b)³= a³+b³+3a²b+3ab² ]

2³+1³+3(2)²(1)+3(2)(1)²

8+1+12+6

27

Answer 2

Answer:

f(x)= ( 2x+ 1)^3

f = 1 ( given)

f(1)= ( 2(1) +1)^3

= ( 2 + 1) ^3

= ( 3 )^3

= 27

f = 27
