Question

PLS HELP!!

Answer 1

Option a: Quadratic expression

Explanation:

The expression is $-2x^{2} +11$

Option a: Quadratic expression

The quadratic expression is an expression in which the highest power or degree of a variable is 2.

Thus, from the expression $-2x^{2} +11$ the highest power of the variable is 2.

Hence, the expression is quadratic

Option a is the correct answer.

Option b: Linear expression

The linear expression is of the form $y=mx+b$

Since, the expression $-2x^{2} +11$ is not of the form $y=mx+b$, it is not a linear expression.

Hence, Option b is not the correct answer.

Option c: Cubic expression

The cubic expression is an expression in which the highest power or degree of a variable is 3.

Since, the expression $-2x^{2} +11$ does not have the highest power 3, it is not a cubic expression.

Hence, Option c is not the correct answer.

Option d: Exponential expression

The exponential expression indicates the number of times the base is used as a factor.

Since, the expression $-2x^{2} +11$ does not indicates the number of times the base is used as a factor, it is not exponential expression.

Hence, Option d is not the correct answer.
