At what value of x does the graph of the following function f(x) have a vertical asymptote? f(x)= 2/x-2

At the values of x which makes the denominator zero.

That is x = 2

The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
