Answer:
when the survey was initially conducted the average sales of smartphones was 1.7 million units
Step-by-step explanation:
The average annual sales of smartphones is given by function

Exponential growth function is given by

Where a= initial value
b = growth factor , b= 1+r where 'r' is the growth rate
x is the time period
Now we compare f(x) with P(n)
the value of a= 1.7 that is the initial value.
So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
The slope of the function is 2!
Since we know the slope is 3 we have part of the equation already (y=3x+b). Now we need to find the y-intercept. To do that we plug in the point that was given to us in the question and solve for b.
0=3(-5)+b
0=-15+b
15=b
Now that we have the y intercept we can put the equation together.
Answer: y=3x+15
