First graph it
#1
Maximum height is the y coordinate of vertex
- (2,144)
Max height
- 144m
#2
Time is the x coordinate of vertex
- 2s
#3
- y is 0
x intercepts are the solutions
- (-1,0)U(5,0)
Take it positive
- t=5s
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
You want to isolate the variable 'y'.
Subtract 10 to both sides:
Divide -3 to both sides:
Subtract 10 to both sides:
Divide -3 to both sides:
