Use the functions f(x) = x + 7
and
g(x) = 2x − 9
to find the indicated function.
(g−1 ∘ f −1)(x)

Step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
