Question

Please help me with this

Answer 1

A represents f(x) and B represents g(x)

Explanation:

choose a value for x, substitute , say x = 1 into both f(x) and g(x) , then check the values obtained on the graph.

f(x) = 100 ×
`((3)/(5)) ^(1)` = 100 ×
`(3)/(5)` = 20 × 3 = 60

thus (1, 60 ) is a point on the graph of f(x)

the point (1, 60 ) is on graph A

g(x) = 100 ×
`((2)/(5)) ^(1)` = 100 ×
`(2)/(5)` = 20 × 2 = 40

thus (1, 40 ) is a point on the graph of g(x)

the point (1, 40 ) is on graph B
