Does anybody know this ??

Transformations:

1.) The -4 moves your y-intercept down 4 units. Without the -4, your y-intercept would be (0,-1)

2.) The -2 in the fraction moves your x-intercept to the to the right 2 units. Without the -2, your x-intercept would be (1/2,0)

Domain:

(-∞,2) ∪ (2,∞)

Range:

(-∞,-4) ∪ (-4,∞)

Vertical Asymptote:

x=2

Horizontal Asymptote:

y=-4

X-Intercept:

(5/2,0)

Y-Intercept:

(0,-5)

the answer to the expression is 83
