The series converges to -1.5.

Step-by-step explanation:

This is a geometric series, so it converges if the number in parenthesis is between -1 and 1.

-1 < -3/5 < 1, so the series converges by the geometric series test.

Now we can plug this into the calculator (on TI-84, it's Math->0 summation) to find that the sum is -1.5. You can use 100 or another big number as a placeholder for infinity.

a negative exponent is translated as follows:

so, we have

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
