Answer:
reflection over the x-axis and a vertical compression by a factor of 8
Step-by-step explanation:
The parent function is given as

The transformed graph has equation:

The factor of 8, indicates a vertical stretch.
The negative sign indicates a reflection in the x-axis.
Therefore the transformation is a reflection over the x-axis and a vertical compression by a factor of 8.
22.8 grams of element will be remaining after 7 minutes
Further explanation:
Given

The element reduces (1-22%) in one minute.
The process will be repeated 7 times for 7 minutes
If we have to calculate the amount of element after 7 minutes
then the total reduction will be: (1-22%)^7

22.8 grams of element will be remaining after 7 minutes

Answer: x intercept is -3
y intercept is -9
Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept
6x+2(0)=-18
divide both sides by 6, and get -3 as an x intercept
