4. The price of a stock started out at $150 per share and has declined to 2 weeks. The function that models this decline is f(x)=150(0.75), where x represents time in
weeks, and f(x) represents the price of the stock. What is the rate of change in the price of the
stock over the interval [1, 4]?
What is the rate of

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
