a particle moves along the x-axis so that its velocity in feet per second at time x, in seconds, is modeled by the quadratic function y = 2x2  − 10x + 12. what does the number 12 represent for the quadratic function?   the particle is 12 feet above the x-axis initially.  the particle's initially velocity is 12.  the particle is 12 feet to the left of the origin initially.  the particle's terminal velocity is 12.

For this case we have the following equation:

Where, we have the following variables:

x: time in seconds

y: speed in feet per seconds

For the initial velocity, we evaluate x = 0 in the given equation:

Therefore, the initial speed is 12 feet per second.

The particle's initially velocity is 12.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
