Use the function rulef(x)=3x-2 . Find the output f(1.5).

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...?

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

ok...thank you

To find the output of a function, you simply need to substitute the given value into the function and evaluate it. In this case, we need to find the output of the function f(x) = 3x - 2 when x = 1.5.

To do this, substitute x = 1.5 into the function:

f(1.5) = 3(1.5) - 2

Now, compute the expression:

f(1.5) = 4.5 - 2

f(1.5) = 2.5

Therefore, the output of the function f(1.5) is 2.5. Hence, the correct answer is A. 2.5.
