there are two symmetric points on a parabola at (3,-2) and 1 point
(7,-2). which option represents the parabola's axis of
symmetry? *
o x= 5
o x = 3
o x = 4
o
x = 2
1 point
which point represents the vertex of the given quadratic
function? hint: the axis of symmetry is x = 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

add 8+12 to get a simplified answer of 12r-20

correct answer was 0.5
