2. Review of Graphing for Quiz Prep
2
f (x) = ax + bx + c
You can always make a table of values!
To be more efficient:
x = b
1. Find quot;axis of symmetryquot;
2a
2. Find the vertex plug x in to find y
3. Pick two x values to the right and find
the y values by plugging in
4. Use symmetry
4. Projectile Motion
2
h(t) = 16t + vot + ho (English units)
2
h(t) = 9.8t + vot + ho (S.I. units)
h(t) => height as a function of time
vo => initial velocity
ho => initial height
5. Projectile Motion
2 (English units)
h(t) = 16t + vot + ho
2
h(t) = 9.8t + vot + ho (S.I. units)
Some fireworks are fired vertically into the air
from the ground at an initial velocity of 80 feet
per second. Find the highest point reached by the
projectile just as it explodes.
