Correct option:
[tex]2x^2+3x-13x-1[/tex]
A quadratic function is given by the form:
[tex]f(x)=ax^2+bx+c \\ \\ Being \ a,b,c \ any \ real \ constants[/tex]
On the other hand, a quadratic equation is given by the form:
[tex]ax^2+bx+c=0 \\ \\ Being \ a,b,c \ any \ real \ constants[/tex]
And a quadratic expression is given by the form:
[tex]ax^2+bx+c \\ \\ Being \ a,b,c \ any \ real \ constants[/tex]
As you can see, when talking about the term quadratic the higher degree of the polynomial is 2. The options are:
[tex]1. \ 6x^4-5x^3+3x^2-7x-8 \\ \\ 2. \ 5x^3+3x^2-7x-8 \\ \\ 3. \ 2x^2+3x-13x-1[/tex]
So the only option that meets our requirement is:
[tex]2x^2+3x-13x-1[/tex]
