For this case we have three different functions in three different intervals.
Let's write the function for each interval.
We have:
For t = [0,5]
v (t) = 23 m / h
For t = [5,10]
v (t) - vo (t) = m * (t - to)
m = (46-23) / (10-5)
m = 4.6
We choose an ordered pair:
(to, vo (t))) = (5, 23)
Substituting:
v (t) - 23 = (4.6) * (t - 5)
Rewriting:
v (t) - 23 = (4.6) * (t - 5)
v (t) = 4.6 * t - 23 + 23
v (t) = 4.6 * t
For t = [10, 5]
v (t) = 46

Answer:
5 roots (answer C)
Step-by-step explanation:
Any polynomial should have in the Complex Number System, as many roots as the polynomial's degree.
In our case, since we are dealing with a polynomial of order 5 (degree 5), it should have 5 roots in the Complex Number System.
