The following function gives the height h metres, of a batted baseball as a function of the time, t seconds, since the ball was hit. h = -4.5t^2 + 13.5t + 5.875 a) What is the physical significance of the 5.875? Prove this is true. b) Determine the characteristics of the quadratic function (hint: Write in standard form). c) What is the geometric significance of the left t-intercept of the graph? Why does this point have no real physical meaning?

5.875 is a height about the ground that the ball is hit from
b) I don't understand what b is asking c) this is where h=0, in other words where ball hit the ground
how would i write the equation in standard form: y=a(x-h)^2+k ?
