Jamaal bounces on a tampoline. his height as a function of time is modeled by y=-16x^2+20x+4. which statement best describes the function?

A) if $50000 is invested in a bank account that pays 9.3% of interest compounded on a six-monthly basis, how much money will be in the account after 3 and 12 years? b) if matusalen's father had put $2.0 in the bank when he was born and there, how long would matusalen have had to his death (969 years later) if the interest was 7% per year composed each month and weekly?

This is different from the first one can someone me

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10
