For all functions of the form f(x) = ax2 + bx + c, which is true when b = 0?

For all functions of the form f(x) = ax2 + bx + c, the y-intercept will always be the vertex.

step-by-step explanation:

the shape,the size and the distance

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)
