Matteo is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satellite can be modeled by y^2=6x where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite? (–1.5, 0) (0, –1.5) (0, 1.5) (1.5, 0)

The equation is written in the form of a hyperbola (y^2 = 4ax). The focus of a hyperbola is (-a,0) As 4ax = 6x, a = 1.5. Therefore the focus is (-1.5, 0)
