3-1 f(x) in quadratics

To find the f(3) = $x^2+x-6$ insert 3 everywhere x is found in the equation: f(3) = $\left(3\right)^2+\left(3\right)-6$   True or False?

• TRUE (Pick me!)
  

• False, but not what you should be picking.

• False, but this is an incorrect answer.

• All of the above

To find the f(-2) = $x^2+x-6$ insert -2 everywhere x is found in the equation: f(-2) = $\left(-2\right)^2+\left(-2\right)-6$   True or False?

• T R U E 
  

• false, but not what you should be picking.
