Answer:
Option 3 - f(x)= 4x,
Step-by-step explanation:
To find : Which two functions are inverses of each other?
Solution :
Two functions are inverse if
Now, we find one by one
1) f(x)= x, g(x) = -x
Not true.
2) f(x)= 2x,
Not true.
3) f(x)= 4x,
i.e. is true.
So, These two functions are inverse of each other.
4) f(x)= -8x,
Not true.
Therefore, Option 3 is correct.
General Idea:
The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.
The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The theorem says that when the lines are parallel, that the alternate interior angles are equal.
Applying the concept:
Angles PBC and BAD are congruent by the <u>Corresponding Angle Theorem</u>.
Angles ABC and BAT are congruent by the <u>Alternate Interior angle Theorem</u>.
