*A model for the height of a toy rocket shot from a platform is y=-16x^2+145x+7, where x is the time in seconds and y is the height in feet.
a)Graph the function
b)Find the zeros of the function( i get a weird root)
c)What do the zeros represent? Are tehy realistic? (answered)
d)About how high does the rocket fly before hitting the ground? explain???
*what are multiple zeroes? Explain how you can tell if a function has multiple zeroes.
*A polynomial equation with rational coefficeints has root of 7 and negative root of 3. Explain how to find two additional roots and name them.
I know that hte additional roots will be negative root of 7 and positive root of 3... what do you mean by name them?
Thanks for the help
