function h is a transformation of the parents tangent function such that h(x)=-tan(1/2x). Which graph represents function h?

Nuetrik [128]

The graph that represents function h is the graph in; Option C

<h3>How to Interpret Graph Transformations?</h3>

The parent function is; f(x) = tan (x)

The transformed function is; h(x) = -tan(¹/₂x)

Now, from general tangent function we know that; y = tan(Bx)

Thus, period = π/(¹/₂)

From the given transformation that produced the h(x) function and when we look at the given graphs, the one that represents the function h is Option C.
