A) Business means the process of earning money, so she earned $350 at first time, so her initial value would be: $350

Rate of change = 750 - 350 / 350 * 100
= 400 / 350 * 100
= 40000 / 350
= 114.28

Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57

In short, Your Answer would be 28.57% per year

B) Equation would be: Y = x + 0.2857x
Where, x = number of year

Hope this helps!

Consider functions f and g defined by the graph and the table.<br><br> Please help me ASAP
Fed [463]

Answer:

Step-by-step explanation:

Given are two functions represented one by graph and another by table

We can check the given statement one by one

1) f(2)=18 : f(0) =15

Average rate of change = \frac{18-15}{2-0} =1.5

For g(x) avg rate of change

=\frac{g(2)-g(0)}{2-0} \\=4

Hence g has a higher average rate of change than f.

True

2)f is linear and eventually exceeds g (f(0)>g(0) . True

3) True because y intercept is 10 for f while 8 for g

4) True because f(3) <g(3)

5) False both cannot be linear
