Evaluate y for several values of x; plot the corresponding coordinate points; joint the points with as smooth a line as you can.

Explanation:

For color(black)(y=(x+1)^2-4 I picked the points:

{: (color(black)(x),"|",color(white)("X")color(black)(y)), ("----",,"----"), (-1,"|",-4), (color(white)("X")0,"|",-3), (-2,"|",-3), (color(white)("X")1,"|",color(white)("X")0), (-3,"|",color(white)("X")0), (color(white)("X")2,"|",color(white)("X")5), (-4,"|",color(white)("X")5) :}
