A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could represent
the weekly profit in thousands of dollars, y, when the company sells x items?
Oy2 - 4x2-100
y=-x2 + 50x-300
O x=-y2+ 60y-400
O x2 --6y2+ 200

add an image

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
