The answer is D. If you plug in -6 for x (the x-value where the asymptote lies), only this equation will yield 1/0 for x=6. This means that D is the correct answer.

As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",

$\bf \stackrel{f(x)}{y}=\cfrac{1}{2}x+4\qquad \qquad \stackrel{inverse}{\underline{x}=\cfrac{1}{2}\underline{y}+4}\implies x-4=\cfrac{1}{2}y
\\\\\\
2x-8=\stackrel{f^{-1}(x)}{y}
\\\\\\
f^{-1}(4)=2(4)-8\implies f^{-1}(4)=0$

just olya [345]

Answer:

Step-by-step explanation:

4x+6<= -54

4x <= -60

x <= -15 [The point -15 is included, so it must be a solid dot]

----------------

5x + 7 > -18

5x > -25

x > -5 [The point -5 is NOT included, so it should be an empty dot.]

Solution C seems the best.
