The parent function f (x) = x2 is reflected across the x-axis, vertically stretched by a factor of 3, and translated right 7 units to create g(x). Use the description to write the quadratic function in vertex form.
O A. g(x) = -3(x – 7)2
O B. g(x) = 7(x + 3)?
O c. g(x) = 3(x – 7)
O D. g(x) = -3(x + 7)?

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

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)

step-by-step explanation:
