1) Least value of f(x) will be 7/12
2) Least value of f(x) will be 6
3) Least value of f(x) will be -7
4) Least value of f(x) will be 9
5) This function f(x) has a least value
6) Greatest value of f(x) will be 7/12
7) This function f(x) has a greatest value
8) Zero is the least value of the function
9) The least value of the function is negative
10) None of these
Solution
Since coefficient of x^2 is positive so the function will have a least value

Mathematics has 25%formulas, 25%proofs and apply 25%thinking and 25%efforts.
In real life situations proofs are nothing but already existed stories(we know the solutions from all experienced people).
formulas are nothing but goals. we have so many goals b
