The vertex is 
Explanation:
The equation is 
To find the vertex, we need the equation in the form of 
Dividing each term by 2 in the equation
Now, completing the square by adding and subtracting 1, we get,
The first three terms can be written as 
,
![f(x)=2[(x+1)^{2}+\frac{1}{2} ]](https://tex.z-dn.net/?f=f%28x%29%3D2%5B%28x%2B1%29%5E%7B2%7D%2B%5Cfrac%7B1%7D%7B2%7D%20%20%5D)
Multiplying 2 into the bracket, we get,
This equation is of the form
Now, we shall find the vertex 
Thus, 
and 
Thus, the vertex is
Answer:
1
Step-by-step explanation:
To find x, set both equations equal to each other.

Easy
leading coefiencet means highest power coefient
degree is the power of the highest exponent
5th degree and leading coefienct is 4
means highest exponet is 5 and the coefienct is 4
means any thing with 4x^5 such that there is no x^n where n>5
4x5 + 3x + 1 is the answer (2nd one)
