Write an equation whose graph has no x intercept? explain how you know there is no x intercept? ? i need pleas

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

What’s the range cuz i can’t find it?
