Hello I need help with one of my class thank you in advance

1. An object is launched up from a platform. The equation for the object's height "h" at time "t" seconds after launch is represented by the function: h(t) =-1.27t2 + 11.1t + 10.3, where h is in meters. Round two decimal places. A) After how many seconds does object reach the max height? B) What is the max height? C) What is the height when the object hits the ground? D) After how many seconds does the object hit the ground? E) What is the x and y-intercepts for this situation? F) What is the domain for this problem? G) What is the range for this
