Explanation:
#"in general adding a value say k to f(x) is equivalent to"#
#"a vertical shift"#
#"that is " f(x)+-k" moves f(x) vertically"#
#uarr" if + k" darr" if -k"#
#rArr"the graph of " g(x)" is the graph of f(x) moved vertically up by 1 unit"#

Explanation:
Compare the graphs:
graph{4^x [-10, 10, -5, 5]}
versus:
graph{4^x+1 [-10, 10, -5, 5]}
