use the function rule f(X) =3x-2 find the output f(1.5).
A: 2.5
B: -2.5
C: 6.5
D: - 6.5
I Guess A. Please help!
I Really need help, Plz respond.
Just plug in the 1.5 as the x value, that's what f(x) means. Whenever there is a number within the brackets, it counts as the x value.
so is it c?
where are you Ellen. :(
I still need help to.
f(1.5)=3(1.5)-2
I did what you said Ellen and got A. Am I right?
thx bobpursley, is A right?
ITs A!!!
To find the output of a function, you need to substitute the given value into the function and solve for the result. In this case, you are given the function rule f(x) = 3x - 2 and you need to find f(1.5).
To find f(1.5), substitute x = 1.5 into the function:
f(1.5) = 3(1.5) - 2
f(1.5) = 4.5 - 2
f(1.5) = 2.5
So, the output of f(1.5) is 2.5. Therefore, the correct answer is A: 2.5.
