Answer:
Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations. 
Red =  
Blue = 
By graphing those equations, we can determine the solution(s)
The points where the graphs intersect would be your coordinates to derive your solution 
Red = (1.864, 1.966)
Blue = (-0.427, 1.254)
The solutions would be the x-value of the ordered pair, in this case, 
x = 1.864 AND x = -0.427
 
        
             
        
        
        
Answer:
The value of Lucys house  at the start of 2017 is 231525.
Step-by-step explanation:
It is given that the initial value of Lucys house is 200,000. The  at the start of 2017.
The exponential function is defined as

Where, P₀ is initial value, r is growth rate, t is time in years.
The value of house is defined by the function

Where, t is number of years after 2014.

The difference between 2017 and 2014 is 3 years.

Therefore the value of Lucys house  at the start of 2017 is 231525.
