Which could be the entire interval over which the function, f(x), is positive? f(x) 2. 0 -3 -2 -1 0 1 2 3 4 220 ○ ( 0, 1) 0 (-2, 1) O (0, 0) 0 (1, 4) -8 -10 -20

table 3 represents a direct variation function. : )

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
