the possible values of k?
NGiven f(x) = 2x + ax? - 7a²x - 6 a?, determine whether or not x - a and x + a are
factors of f(x). Hence find, in terms of a, the roots of f(x) = 0.

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)
