Question 874670

What is the maximum value of f to four decimal places graphically, f(x)=100x-11x^2+2?
<pre>
Maximum value of f(x), or y occurs at {{{x = -b/2a}}}, with:
a being - 11
b being 100
{{{x = - b/2a}}} ----- {{{x = - (100)/2(- 11)}}} ------ {{{x = 4.545454545}}}
With x being 4.5454545454, f(x) = {{{100x - 11x^2 + 2}}} becomes:
f(x) = {{{100(4.54) - 11(4.54)^2 + 2}}}
{{{highlight_green(f(x) = 229.2724)}}}
You should be able to graph the parabola based on the coordinates of the vertex being (4.54, 229.2724)
