A dolphin jumps straight into the air during a performance. The dolphin's height y (in feet) after t seconds can be modeled by y = −16t2+24t. a. How many seconds is the dolphin in the air? The dolphin is in the air for seconds. Question 2 b. The dolphin reaches its maximum height after 0.75 second. What is the maximum height of the jump? The height of the dolphin is feet (above water level) at 0.75 second.\

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
