Question

If f(x) = 2(3^x) + 1, what is the value of f(2)? (1) 13 (3) 37 (2) 19 (4) 54

Answer 1

54 that’s the answer

Answer 2

Answer:

Given  

F ( x ) = 3 x 2 + 1 , to find  F ( − 2 ) , we have to just put

x = − 2  in the formula for  F ( x ) .

therefore , F ( − 2 ) = 3 ( − 2 ) 2 + 1 = 3 ( 4 ) + 1 = 13  .
