Given:


f(x)=2x^2+5x+2

Find-: Continuous interval.

Sol:


y=2x^2+5x+2

Domain: Domain defines all possible input values for the function.

So Domain of function is all real value.


x\in\Re

So function gives some output for all real values so it's continuous in all real values.

So interval for continuous is:


\begin{gathered} \text{ Continuous on }\Re\text{ }(\text{ all real value\rparen } \\ \\ \text{ Interval \lparen-}\infty,\infty) \end{gathered}
