Answer:
1
Step-by-step explanation:
We will consider only the last digit multiplication and the pattern.
When we multiply 843,219 with 843,219, we have
9 * 9 = 81 [1 is important]
1 * 9 = 9
9 * 9 = 81 [1 is important]
So when we multiply them out with each other, we have a pattern of
9, 1, 9, 1 ... goes on
So if we multiply 100 times, what will be the last digit of the series 9, 1, 9, 1 .... it will be 1
hence, last digit is 1

Answer:
im guessing 3 because it makes the most sense to me
hope it helped
Step-by-step explanation:
To start, note that the roots of a function have to do with how many times the function passes through the x-axis.
When you look at the graph above, notice that it passes through the x-axis 3 times, at the points (-6,0), (-4,0), and (3,0).
Knowing this, you can conclude that your answer would be choice B.)3
