6. A ball is thrown into the air with an upward velocity of 24 ft/s. Its height (h) in feet after t seconds is given by the function h = –16t2 + 24t + 5. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary. (1 point) a. 1.5 s; 5 ft. b. 0.75 s; 32 ft. c. 0.75 s; 11 ft. d. 0.75 s; 14 ft.

23 y=ax+b x=0 => y=2 2=a*0+b b=2 x=1 => y=3 3=a*(1)+b 3=a2 a=1 y=x2 It's a linear function
