Answer:

Step-by-step explanation:
18 min = 0.3 h
Car 1 started 0.3 h before Car 2.
Let t = time of Car 2. Then
t + 0.3 = time of Car 1
Distance = speed × time, and both cars travel the same distance. Then

Answer:
y = tan(x +π/2)
Step-by-step explanation:
It can be helpful to start with a simple sketch of the function you have and of the tangent function. Then, you can see the relationship.
The tangent function is always rising, has vertical asymptotes at -π/2 and π/2, and has a zero crossing at x=0.
The function we want is always rising, has vertical asymptotes at x=0 and x=±π, and a zero crossing at x=-π/2.
We can create the function we want by shifting the tangent function to the left by π/2. The formula that does that is ...
y = tan(x +π/2)
