Answer:
[tex]f\mleft(x\mright)=x^4[/tex]Step-by-step explanation:
The Fundamental Theorem of Algebra states that the degree of a polynomial is the maximum number of roots the polynomial has.
For polynomials, the degree of the polynomial represents how many times the function crosses the x-axis or the zeros it has. Then if we want to graph a 4th degree or higher polynomial that crosses the horizontal axis no more than once:
[tex]f\mleft(x\mright)=x^4[/tex]
