Answer:

f(3)=21

Explanation:

this is quite simple. To start off the equation is

$f\left(x\right)=2x^2+x$

All you do now is just plug 3 into x because you are trying to find f(3).

$f\left(3\right)=2\left(3\right)^2+3$

after that you simplify it to

$f\left(3\right)=2\left(9\right)+3$

Then you multiply.

$f\left(3\right)=18+3$

after that, the final step is just to add :)

$f\left(3\right)=21$

therefore, the final answer is:

$f\left(3\right)=21$

I hope this helps!
