The equation and graph of a polynomial are shown below. The graph reaches its maximum when the value of x is -2. What is the y-value of this maximum?
the equation
y=-x^2-4x-1
I think it's -2. Am I right?

The question is asking you to evaluate at $x = -2$.
Your equation is $f(x) = -x^2 -4x - 1$
What is the value when $x=-2$?
$$f(-2) = -(-2)^2 - 4(-2) -1$$
Hint: it does not equal to your guess of $-2$.
