Use the graph of f(x) to determine whether the function is one-to-one. If it is, find a formula for its inverse. X+6
f(x) =
X-7
Is the function one-to-one ?
Yes
Ο Νο
Select the correct choice below and fill in the answer box within your choice if necessary.
O A. The inverse function is f-'(x) = 1. (Simplify your answer.)
OB. The function is not one-to-one.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

explanation:

remove parenthesis:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

have a great day
