Consider the function f(x) = /4-x + 10 for the domain (-0, 4]. Find f-1(x), where f-1 is the inverse of f.
Also state the domain of f
-1
in interval notation.

Question 1:
It is given that BC = EC and AC = DC. According to the definition of vertical angles, ∠BCA = ∠DCE. Thus, the two triangles are congruent by SAS. According to CPCTC, BA must be congruent to ED.

Edit this paragraph to make it more "yours"

Question 2:
A and E are base angles.
B and D are legs.
F is the base.
C is the vertex angle.

Have an awesome day! :)
