Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points)
Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points)
Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

y - y1 = m(x - x1)
y - 2 = m(x - 1)
y - 2 = 1(x - 1)
y - 2 = x - 1
y (-2 + 2) = x (-1 + 2)
y = x + 1
Find the y-intercept by substituting x with 0
y = 0 + 1
y = 1

(A) Y-Intercept = 1 (copy and paste all the work I did into the box, you don't want to get points off for not showing work)
The y intercept represents where x = 0
