    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
