A soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second, The equation h = 16t^22 + 90t gives the height h of the ball after t seconds.
Give the domain and range of function
You cannot have negative time ....so the domain is 0 and all positive t [0,+inf)
the range will be 0 through the max of the parabola: + inf (did you forget a ' - ' sign?) [0,+inf)
