To get the answer simply substitute the given value to the given equation
after substituting the value, instead of f (a) it will then become f (-a)
change the value of every "a" in the equation according to the given; which is - a.
after substituting the given the answer will become f (-a) = - 2a^2 - a
solution:
f (a) = 2a^2 + a if f (-a)
f (-a) = 2 (-a) ^2 + (-a)
f (-a) = - 2a^2 - a from addition the operation became subtraction because in math (+) (-) = (-) "positive time negative is negative".
