Consider these four line graphs representing speed in meters/second, where each X-axis is labelled in seconds and each Y-axis is
labelled in meters. What do the four graphs have in common?
A) They all indicate a constant speed.
B) They all indicate an increase in speed.
C) All four graphs have nothing in common.
D) They all represent the same speed in m/s
All four graphs indicate a constant speed. So, they do not all indicate the same speed. Since the slope of each line is constant, we know the the speed represented by each line is also constant or unchanging. It is like having cruise control on your car.
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
