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!

I need a. Correct answer I will mark brainliest
Otrada [13]

Answer:

Option (A)

Step-by-step explanation:

By satisfying the equation of a function 'f' by each coordinates given in the options we can get the point which lies on the graph of f(x) = 2\times (5)^x

Option (A). (1, 10)

f(1) = 2\times (5)^1

10 = 10

True.

Therefore, point (1, 10) lies on the graph.

Option (B). (0, 10)

f(0) = 2\times 5^0

10 = 2

Not true.

Therefore, point (0, 10) doesn't lie on the graph.

Option (C). (10, 1)

f(10) = 2\times 5^{10}

1 = 19531250

Not true.

Therefore, point (10, 1) doesn't lie on the graph.

Option (D). (0, 0)

f(0) = 2\times 5^0

0 = 2

Not True.

Point (0, 0) doesn't lie on the graph.

Option (A) will be the answer.
