Final answer:
The equation y=8x^4+1 is neither linear nor quadratic.
Step-by-step explanation:
The equation y=8x4+1 is a neither linear nor quadratic equation. It is a polynomial equation of degree 4. A linear equation has a maximum degree of 1, while a quadratic equation has a maximum degree of 2. In this equation, the degree is 4 because the highest exponent of x is 4. Therefore, it is neither linear nor quadratic.
