A.) a restless point moved from point −3.2 to the right at the speed of 0.3 units per hour. where will it be in 20 minutes? plz ! i give 15 points

For this case we can use the following motion equation:
 
 Where,
 rf: final position
 ro: initial position
 v: speed
 t: time
 Substituting values we have:
 
 
 it will be at -3.1 in 20 minutes

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
