Create a polynomial with two terms and a degree of 4

Step-by-step explanation:

The first number's exponenet represents the degree and 2 terms are present, one is 3x^4 and the other is 4x.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
