6.03
8.01
What is the minimum value of |x – 1|, where x ∈ R ?
0
1
2
- 1
A.
0
Given function is a mod function.
So any value that will come out of it , would be a positive value or zero.Hence the minimum value of |x – 1| would be zero only.
If f(x) = 3x2 – 5x + p and f(0) and f(1) are opposite in sign, then which of the following is correct ?
-2 < p < 0
-2 < p < 2
1 < p < 2
3 < p < 5
