Question

The graphs of functions f(x) and g(x) = f(x) + k are shown below:

graph of line f of x going through ordered pairs 0, negative 2 and 2, 2. Graph of line g of x going through ordered pairs 0, 2 and 1, 4.

The value of k is ___.

Answer 1

Answer 2

just count the vertical distance between points at the same x. so at x=0 the vertical distance is 4. so k is 4 , which means that g(x) is always 4 upper than f(x)
