Question 1098025
.
Your steps, your calculations and your answer are PERFECTLY correct.


Their answer is wrong.


Actually, their answer "-1" fits for x-intercept.

So, it looks like the error is on their side.



--------------------
<U>comment from student</U>.  I'm sorry to be a pest, but in my previous response to you, I mentioned that I couldn't figure out 
how to calculate -1 as the x-intercept for the above polynomial function: S(x)= 1/2(x-1)^3 +4. So this is what I just tried: 
1/2(x-1)^3 +4 = 0 --->  1/2(x-1)^3 = -4 --->  (x-1)^3 = -8 x-1 = cube root negative 8 (I don't have the symbols for that; sorry) 
x-1 = -2 --->  x = -2 +1 --->  x = -1 


Is this correct? Again, let me know if it's improper for me to be asking you more questions via email this way, 
and I will re-submit this as another question on algebra.com. Thank you.
