High school math what is the approximate value of the function at x = 3
a) 2
b) 1
c) 1.8
d) 1.5

C / 1.8

Step-by-step explanation:

Because x = 3 then , you see it's an approximately y>1.5

and of course it's not exactly 2

so, the answer will be 1.8

idk

step-by-step explanation:

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
