# How do you find the axis of symmetry, graph and find the maximum or minimum value of the function f(x)=1/3(x+6)^2+5?

$\frac{{x}^{3}}{3} + 4 x + 17$ This the equation you will get when you expand the bracket and simplify.
$\frac{1}{3} {\left(x + 6\right)}^{2} - 5$ This is the equation when you complete the square. To find the X and Y value. Take what is in the bracket and equate it to zero. So, in this case, it is X+6=0 and X=-6.
