Victor is enlarging a poster for a school baseball match. The graph below shows the size y of the poster after x enlargements: graph of y equals 1.8 to the power of x What does the y-intercept of the graph represent?

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.
