Question

f(x) = twenty-four over the quantity of 3 x minus two. Find f(-2).

Answer 1

Hello and Welcome to OpenStudy! :)

finding f(-2)
means that you plug in (-2) for x
so 24 / (3(-2) - 2)) = ?

Answer 2

f(-2)=24/3(-2)-2

Answer 3

x−223=y


you got from
y=243x−2

remember you can only subtract and add fractions when they have the SAME denominator.
Here, you have to treat (3x-2) as one term.
