Question

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?

Answer 1

Answer:C

Step-by-step explanation:

Original size of the picture

Answer 2

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.
