If f(x) and f^-1(x) are inverse functions of each other adn f(x) - 2x+5, what is f^-1(8)?

Step-by-step explanation:

If y=f(x)=2x+5, to find the inverse function express x n terms of y:

Now, change y into x and x into y:

Substitute x=8 into expression:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
