After 10 hours of work, she makes a total of $500
The vertex form of the function is f(x) = -2(x-4)^2 + 2
<h3>Vertex form of a function</h3>
The standard vertex form of a function is expressed according to the expression;
f(x) = a(x-h)^2+k
where
a is a constant = -2
(h, k) is the vertex = (4, 2)
Substitute
f(x) = -2(x-4))^2+2
f(x) = -2(x-4)^2 + 2
Hence the vertex form of the function is f(x) = -2(x-4)^2 + 2
