Question

The graph shows how the length of a buildings shadow at a certain time of day is related to the height of the building.

Answer 1

a. answer is function and relation

b. 3/4x

c. not sure of the answer. but I think it was 2 and 1

Answer 2

A. the graph represents a relation because it contains ordered pairs (x,y). It is also a function because there are no repeating x values.

B. (0,0) (8,6)
slope = (6 - 0 ) / (8 - 0) = 6/8 = 3/4
so ur equation is : y = 3/4x or f(x) = 3/4x <===

C. the variable x represents the height of the building and the variable y (or f(x)) represents the total length of the shadow
