write a function of the form f(x) = a/x-h + k

with vertical asymptote is x=-2, horizontal asymptote is y=-5. the graph expands vertically by a factor of 2 and reflects across the x-axis.

Step-by-step explanation:

VA= -2

HA= -5

F(x)= 2(x+5)/-(x+2)

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
