Hey there! :)
Answer:
Choice B.
Step-by-step explanation:
We can eliminate each graph:
a). This is what is known as a step function. This is incorrect.
b). This is an exponential function because the graph is shaped like a geometric equation. This means that the rate of change is exponential. This is the correct choice.
c). This is an absolute value function. This is incorrect.
d). This is a graph of a polynomial. This does not represent an exponential function, which makes it incorrect.
6,824 rounded to the nearest ten is 6,820.
That is because 6,824 is closer to 6,820 than it is to 6,830.

==============================
Explanation:
The hundredth decimal place is two spots to the right of the decimal
For instance, the digit 5 is in the hundredths place for 7.3547
Since the next digit over is not 5 or larger, this means we just keep 7.35 and ignore everything else. We don't round up.
Something like 1.1295 becomes 1.12 after we drop everything after the '2', but we round up to 1.13 because of that 9 being five or larger.
The other 8 problems are handled in a similar fashion.
