The line crosses the y-axis at point (0,2). You know this because the slope intercept form is y=mx+b. y is any point on the y-axis. m is the slope of the line. x is and point on the x-axis. Finally, b is the y-intercept or where the line crosses the y-axis. As a result, your equation has a 2 for b. So, your answer would be: the line crosses the y-axis at point (0,2). 2 being where the line crosses the y-axis.

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 fun

Katyanochek1 [597]

For this case we have the following equation:

$y = 2x ^ 2 - 10x + 12$

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:

$y = 2 (0) ^ 2 - 10 (0) + 12\\y = 12$

Therefore, the initial speed is 12 feet per second.

Answer:

The particle's initially velocity is 12.
