Mr. Phartzy is an avid art collector. He knows the price of art fluctuates greatly over time and
has an art appraiser he consults about the projected value of his paintings.
He just bought two paintings, a portrait and a landscape.
The art appraiser says the projected value of both paintings will follow the model of an

where x: time elapsed since the purchase, in years
f(x): the value of the portrait painting, in dollars
g(x): the value of the landscape painting, in dollars
The portrait is projected to be worth $151 165.44 in 3 years and $259 071 in 10 years.
The landscape painting, which was bought for $300 000 is projected to lose $12 000 in value
in the first year.
Mr. Phartzy sells his paintings when they are projected to be of equal value.
Will Mr. Phartzy make a profit or suffer a loss
