#### Explanation:

Given:

#g(x) = (x^2-6x+8)/(x+2)#

Divide the numerator by the denominator by grouping:

#g(x) = (x^2-6x+8)/(x+2)#

#color(white)(g(x)) = (x^2+2x-8x-16+24)/(x+2)#

#color(white)(g(x)) = (x(x+2)-8(x+2)+24)/(x+2)#

#color(white)(g(x)) = ((x-8)(x+2)+24)/(x+2)#

#color(white)(g(x)) = x-8+24/(x+2)#

From this alternative expression we can see that

graph{(y-(x^2-6x+8)/(x+2))(y-x+8) = 0 [-79.6, 80.4, -45.64, 34.36]}
