Question

Function f is a linear function and function g is defined by g(x) = f(x) + k. If the value of k is 7, how does the graph of g compare with the graph of f?

The graph of g is the graph of f
Choose...
translated up 7 units.
translated left 7 units.
translated right 7 units.
translated down 7 units.
stretched vertically by a scale factor of 7.
stretched horizontally by a scale factor of 7.

Answer 1

translated up 7 units.

Adding 7 to the function values shifts every y-value up by 7, so the graph of g is the graph of f moved vertically up 7 units.
