Classify the expression: -2x^2 + 11 A) quadratic expression B) linear expression C) cubic expression D) exponential expression

Below

Step-by-step explanation:

-2x^2 + 11 is a quadratic equation since the degree is 2.

It's not a linear one since it does not give a straight line after graphing it

A

Step-by-step explanation:

For this problem, let's think about the properties of the listed expressions.

We can eliminate B. We know that a linear line is a straight line. It doesn't curve at all. A linear line should not have a power such as the one in the problem. The only power it should have is to the power of 1. Therefore, we can eliminate B.

We can eliminate C. A cubic expression has a cubed in it, meaning it is to the power of 3. The given problem is in power 2. Therefore, we can eliminate C.

We can eliminate D. Though you may think this is an exponential expression because the given expression has an exponent, this is not the case. An expoenetial function actually has x as the exponent, not a number. Therefore, we can eliminate D.

Since we have eliminated D, A is the correct answer.
