Question

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k.

k = _______ .
Graph of f of x and g of x.
f of x equals 1 over 3 x minus 3 and g of x equals 1 over 3 x plus 1.

Answer 1

Answer: 1


`f(x) = (1)/(3x)`

`g(x) = (1)/(3x)+1`

g(x) is in the form f(x)+k where k = 1. To go from f(x) to g(x), shift the entire graph up 1 unit.
