For this case we have the following function:
y = 1.8 ^ x
The intersection with the y axis occurs when x = 0.
We have then:
y = 1.8 ^ 0
y = 1
In this case, the intersection with the y-axis represents the original size of the poster.
Answer:
the y-intercept of the graph represents:
the original size of the poster.
