Projectile motion describes how objects move through the air after being launched, like when a ball is thrown or an arrow fired. After launching, the only force acting on the projectile is gravity ...

A dot plot or dot chart consists of data points plotted on a graph. The Federal Reserve uses dot plots to show its predicted interest rate outlook.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

Example Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4. Writing y = x 2 6 x + 4 in completed square form gives y = (x 3) 2 5.
