Stock market investment of $10,000 was made in 1970 during the decade of the 1970s the stock lost half its value beginning in 1980 the value increase until it reaches $35,000 in 1990 after that its value has remained stable. Let v (d) denote The value of stocks in dollars as a function of the date d.

A- what are the value of v(1970) v(1980)v(1990) and v(2010)

b- make a graph of v against d label the axes appropriately 

c-estimate the time when your graph indicates that the value of the stock was increasing most rapidly

**11. A Stock Market Investment**

A stock market investment of $10,000 was made in 1970. During the decade of the 1970s, the stock lost half its value. Beginning in 1980, the value increased until it reached $35,000 in 1990. After that, its value has remained stable. Let \( v = v(d) \) denote the value of the stock, in dollars, as a function of the date \( d \).

a. What are the values of \( v(1970) \), \( v(1980) \), \( v(1990) \), and \( v(2010) \)?

b. Make a graph of \( v \) against \( d \). Label the axes appropriately.

c. Estimate the time when your graph indicates that the value of the stock was increasing most rapidly.
