Answer:

The correct answer is b.

Step-by-step explanation:

if you arrange the data set in ascending order you will have:

x              y

-2            \frac{1}{100}

-1              \frac{1}{10}

0               1

1                10

3               1000

Exponential growth is an increase in a specific way of a data set over time. here, as x increases by a +1, y increases with ×10

What is y^2-6y=0 without using quadratic formula?
boyakko [2]

y^2-6y=0\\ \\ y(y-6)=0\\ \\ y=0...and...(y-6)=0\\ \\ y=0...and...y=6

Since both y squared and 6y have a common factor of y, can put that to the side and divide both the y squared and 6y to get the second step of the work shown above. Separate both the y on the outside of the parentheses and the numbers within the parentheses and set them both equal to 0 as shown in step 3 of the work shown above. Finally solve for y as you would normally. Those two number in step 4 should be your final answer.
