Answer:

Step-by-step explanation:

y = 3x - 5.....input values are x and output values are y

so if ur input (x) is 2.....sub 2 in for x and find ur output (y)

y = 3x - 5

y = 3(2) - 5

y = 6 - 5

y = 1 <=== ur output value

Part 1:

Given that a<span> store had 235 MP3 players in the month of January and that every month, 30% of the MP3 players were sold and 50 new MP3 players were stocked in the store.

</span>The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and <span>the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.

Therefore, the </span><span>recursive function that best represents the number of MP3 players in the store f(n) after n months is given by </span><span>f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0



Part 2:

The average rate of change of a function from a to b is given by

average \ rate \ of \ change= \frac{f(b)-f(a)}{b-a}

Given that the </span><span>equation showing the value of her investment after x years is given by

f(x)=500(1.05)^x

Thus, </span><span>the average rate of change of the value of Sophia's investment from the second year to the fourth year is given by

Average \ rate \ of \ change= \frac{f(4)-f(2)}{4-2}  \\  \\ = \frac{500(1.05)^4-500(1.05)^2}{2} = \frac{607.75-551.25}{2}  \\  \\ = \frac{56.5}{2} =28.25

Therefore, the </span><span>average rate of change of the value of Sophia's investment from the second year to the fourth year is 28.25 dollars per year.</span>
