well, to graph this, substitue different numbers for x, to graph it

plug in x and solve.
x = -2
x = -1
x = 0
x = 1
x = 2
you'll get a general idea of how it'll look

@Mathhelp346 the 3 is added to find the value of y.
For example
\[y = 2^{x} + 3\]
x = 0
y = 2^0 + 3
= 1 + 3 = 4
y = 4
(0,4) would be one coordinate of the graph

and then it would be x=2 and so on

wait is it \[2^{x} + 3 \] or \[2^{x+3}\]

then yea, just keep plugging in values for x, and solve for y
