What this is telling you to do is put 3x + 3 in the question wherever there was an x to start with.
Solution
f(x) = -3x + 4
f(3x + 3) = - 3(3x + 3) + 4
f(3x + 3) = -3*3x + (-3)*(3) + 4
f(3x + 3) = - 9x - 9 + 4
f(3x + 3) = -9x - 5 <<<<< Answer
Hey there!!
f ( x ) = -3x + 4
Find f ( 3x + 3 )
In order to solve this, we will need to substitute 3x + 3 instead of x
...f ( 3x + 3 ) = - 3 ( 3x + 3 ) + 4
...f ( 3x + 3 ) = -9x - 9 + 4
...f ( 3x + 3 ) = -9x - 5
Hence, the answer is -9x - 5
Hope my answer helps!!
