Answer
T is located at the point where the graphs intersect the x-axis. From the graph, the coordinates of T are determined to be (-1, 0).

Answer
The function h(x) is the reflection of f(x) in the line y = x. Since f(x)=extloga(x), then the reflection gives:
h(y)=extloga(y)
o or [y = a^x] where y is expressed in terms of x.

Answer
The asymptote of h(x) is found by observing the behavior as x approaches the vertical asymptote. Therefore, the asymptote of h(x-3) remains unchanged and is given by:
x=3.

Answer
V is located based on where the asymptotes of g intersect the line y = x. The coordinates of V are calculated as:
V(2+1,2+1).

Answer
To find the coordinates of T', we reflect T around R. Given T(-1, 0) and R(2, 2), we can calculate T'. The coordinates of T' are (3, 4).
