15 <-5x

divide both sides by 5 but since the coefficient of x is negative after dividing the sign changes.

F=5/9c+32<br> Solve for c

arsen [322]

F = (5/9)c + 32
F - 32 = (5/9)c
9(F-32) = 5c

(9(F-32))/5 = c

Which function has an asymptote at x= 39

LekaFEV [45]

Answer:

option B : $f(x)= log_7(x-39)$

Step-by-step explanation:

(a) $f(x) = 7^{x-39}$

For exponential function , there is no vertical asymptotes

General form of exponential function is

$f(x) = n^{ax-b}+k$

$f(x) = 7^{x-39}$

In the given f(x) the value of k =0

So horizontal asymptote is y=0

(b) lets check with option

$f(x)= log_7(x-39)$

To find vertical asymptote we set the argument of log =0 and solve for x

Argument of log is x-39

x-39=0 so x=39

Hence vertical asymptote at x=39
