Step-by-step explanation:

`a) $697.90

b) $161.98 gain

c) 23.2096% annual return rate

Step-by-step explanation:

a) $16.45 for one share. 42 shares will cost 16.45 x 42 = $690.90

As she used a broker and paid $7, the total cost for Tarah would be $697.90

b) After the investment, Tarah's gain is $20.64 per stock and she had bought 42. So the total income would be 20.64 x 42 = $866.88. However, she used a broker to sell the stocks as well, so the total gain would only be 859.88.

Overall, the cost was -697.90+859.88 = 161.98 net gain.

c) The rate of return would be the percentage of the original price of stocks that is equal to the net gain. What we are trying to find here is:

What percentage of 697.90 is 161.98?

We can find this percentage by doing a simple division (161.98/697.90) which gives us an answer of 0.232096

In percentages, multiply this decimal by 100 to get a 23.2096% annual return.

I hope I am correct, but some of the vocabularies may have messed up my answers. Hope it helps!

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
