Answer:
Min: at x = 0, value = c
Max: at x = 0, value = c
Step-by-step explanation:
f(x) = ax² + c
Comparing to a(x - h)² + k,
h = 0, k = c
First we need to determine how far the first biker was able to go.
![distance = 13(8) \\ distance=104](https://tex.z-dn.net/?f=distance%20%3D%2013%288%29%20%5C%5C%20distance%3D104)
This means that the first biker was able to travel 104km, so now we need to find out how far the second biker was able to go. Becasue they both had to meet, we need to subtract the first bikers distance from the total distance between the cities.
![distance = 232-104 \\ distance = 128](https://tex.z-dn.net/?f=distance%20%3D%20232-104%20%5C%5C%20distance%20%3D%20128)
Meaning that the distance that the second biker traveled 128km.
Because
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%20%5Cfrac%7Bdistance%7D%7Btime%7D%20)
we just need to plug the second bikers stats into the equation to find out their speed.
√x = 2 or x = 4
That is your answer

Answer:
Step-by-step explanation:
(5x +x^4) -((3x^4 )+4x), open the parenthesis and distribute the negative sign
5x+(x^4) -(3x^4) -4x, combine like terms
(-2x^4) +x
