Answer 2

Answer:

A- Fiona’s,

B- $6

B- Heidi’s

Step-by-step explanation:

Here, the equation that represents the value of Fiona’s coin, in dollars, x years later is,

f(x) = 3x + 12

Initially, x = 0,

Thus, the value of the coin when Fiona bought,

f(0) = 3(0) + 12 = $ 12,

Also, the graph represents the value of Heidi’s coin, in dollars, x years later.

By the graph, if x = 0 ( initially ),

y = 6

That is, when Heidi bought the coin its value is $ 6,

Also, 12 - 6 = 6

Hence, when they bought their coins, Fiona’s was worth $6 more than Heidi’s coin.
