Question

Given the linear function g(x) = 3x, describe the effect h(x) = 3x – 1 has on the original graph.

Answer 1

x) =g(x) -1 shifts the graph g(x) down 1 unit

Explanation:

g(x) = 3x

When we add to g(x) and make it g(x) +c, we shift the graph vertically,

+c shifts the graph up

-c shifts the graph down

h(x) =g(x) -1 shifts the graph g(x) down 1 unit
