Given f x 3x 4 compute each of the following Show all step
Given f (x) = -3x - 4, compute each of the following. Show all steps, and write your answers as ordered pairs. Write answers as integers or reduced fractions (no decimals). Find f(2) Find x if f (x) = 7
Solution
f(x)=-3x-4
given f(x)=7
then
7=-3x-4
7+4=-3x-4+4
11=-3x
divide by -3
we get x=-11/3 as final answer
