Answer 1

Step 1

The meaning of QUADRATIC EQUATION is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Step 2

We are required to Identify the two tables which represent quadratic relationships.

In a quadratic equation, we have a polynomial in x with degree 2. Hence the result in y or P(x) do get repeated as a polynomial contains x² in it.

Looking at the tables we will observe that;

`\begin{gathered} option\text{ B follows a sequence and is linear} \\ \end{gathered}`
`Option\text{ E is not quadratic but exponential}`
`Option\text{ F is not right}`

The answers will be;

`Option\text{ D and option A}`
