Question 1039286: A quadratic function is given.
f(x) = 1 + x − sqrt of 2(x^2)
a) Use a graphing device to find the maximum value of the quadratic function f, rounded to two decimal places.
Correct: value of f is f(x) = 1.18
I am just not sure how to find the exact maximum value of f, in order to compare it with part (a).

-----
Max occurs at x = -b/(2a) = -1/(2sqrt(2)) = 0.3536..
f(0.3536) = 1.177
----
Max is (0.3536,1.177)
