Function f is an exponential function. It predicts the value of a famous sculpture, in thousands of dollars, as a function of the number of years since it was last purchased. What equation models this function?

As we can observe from the graph:
The curve passes through two points as represented by two dots which are (0,5) and (1,7).
Also , it is given that the function is an exponential function.
As you can observe from the graph , the curve moves upwards that is from second quadrant to first quadrant.
It is an increasing function, because ,As value of x increases, value of y also increases.
The exponential curve is :
y-1 = 4[tex]e^x[/tex] but it does not passes through (1,7).
So, by using desmos graphing , and plotting different graphs of exponential function , i found answer : y = 5[tex]\times (1.4)^x[/tex]
