Identify the vertex of the graph. Tell whether it is a minimum or maximum.

(–1, 0); maximum

(–1, 0); minimum

(0, –1); maximum

(0, –1); minimum

Maximum;  (0, -1)

Step-by-step explanation:

Since the graph is facing the negative way, that means the vertex is a max.

You can think of it as this:  If the curve is on top, it is a max.  If the curve is on bottom, it is a min,

The y value is -1 and the x value is 0

(0, -1)

 Maximum;  (0, -1)

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
