Answer:
This type of transformation is a horizontal stretch.
<em></em>
Step-by-step explanation:
Given
Required
Determine the type of transformation
The first function can be expressed as:
While the second function is:
Solving f(0.5x), we have to substitute 0.5x for x in
So:
The second function is:
<em>This type of transformation is a horizontal stretch.</em>
<em></em>
<em>i.e. f(x) stretched to g(x)</em>

Answer:
D. Runner B; Runner B will catch up to Runner A 3.5 hours after Runner A crosses the starting line.
Step-by-step explanation:
Runner A:
Time it takes for him to finish:
t = 26.2/5.6 = 4.679 hours (to complete race)
.
Runner B:
Time it takes for him to finish:
t = 26.2/6.4 = 4.094 hours
BUT wait, we have to account for the extra .5 hours -- the time it took for him to cross the start line.
t = 4.094 + .5 = 4.594 hours
