Answer:Decreasing
Step-by-step explanation:
Focus only on the 8-10 interval for x. Note that for x=8 , y=1, for x=9, y=0 and for x=10, y=-1. Y is obviously decreasing for .

Answer:
m=4/3 and b=5
Step-by-step explanation:
We want to find the equation of the line passing through (3,9) and (6,13).
We determine the slope using:
Let:
We substitute the points to get:
We now use the formula:
We substitute to get:
Multiply through by 3 to get;
We expand further to get:
This implies that:
We solve for y to get:
Therefore m=4/3 and b=5
1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.
Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:
Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
