# Input functions range of values watch

1. Please can someone help me with Q)27?

On one track I solved that 'x'(the input value), would be greater than 1/8 which would fit the statement. However x>1/8 is not a range of values, so I decided to go down another route.

I factorised x^2-8x+16 then decided to square root both sides. However I think I got lost because my final form doesn't make much sense.

Would it be right if I went with my first option but wrote it as:
x is greater than 1/8 but less than or equal to infinity? Am i missing something?

2. Wheres the question?

4. Oh I can see it now. You're working from the first part is correct, no need to do anything else.
