f ( 1.5 ) = 3 * 1.5 - 2 = 4.5 - 2 = 2.5

Answer : A

so does that mean that 1.5 =2.5...I am sorry I just don't understand this yet...I thought they had to equal the same amount...?
Answered by Bosnian
f ( x ) mean : " f is a function of x "


f ( 1.5 ) are value of FUNCTION 3 x - 2 when x = 1.5


so of f ( 1.5 ) = 2.5
