the stock market rose and fell over a period of five days: 9.8, -3.5, 20.5, 8.6, -7.7. Overall what was the net change in the market?

f(x) = y

f(-3) = -5

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)
