I believe the answer is x^2-4x+1
(I did the problem in my head but it seems correct)
<span> 5 – 6x = 8x + 17
</span>⇔ 5 - 17 = 8x + 6x
⇔ -12 = 14x
⇔ x = -6/7
Answer:
102? hopefully this helps
Answer:
-1
f (x) = x/2 - 3/2
Step-by-step explanation:
I choose to address this question by actually finding the inverse of f(x) = 2x + 3.
1) replace f(x) with y: y = 2x + 3
2) interchange x and y: x = 2y + 3
3) solve this result for y: 2y = x - 3 , or y = (x - 3)/2. This is the same as the second answer choice. Label this result as
-1
f (x) = x/2 - 3/2
