#"see explanation"#

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"#

Graphs

Explanation:

Compare the graphs:

graph{4^x [-10, 10, -5, 5]}

versus:

graph{4^x+1 [-10, 10, -5, 5]}
