f(x) = −x^2 + 8x + 3
---
max occurs at x = -b/(2a) = -8/(-2) = 4
-----
max value y = f(4) = -16+32+3 = 16+3 = 19

the maximum value of the function will be coordinate of vertex; so, write equation in vertex form
...........complete square
so, and ,vertex is at (, )
=>the maximum value of the function will be
