The numeric value of this expression is -6!

To find out what the value of this expression is, let's replace f(x) with f(-3) and perform the given math operations.

$\large \sf f(x) = 12 - 2x {}^(2)$

$\large \sf f(-3) = 12 - 2\cdot (-3){}^(2)$

$\large \sf f(-3) = 12 - 2\cdot 9$

$\large \sf f(-3) = 12 - 18$

$\boxed{ \boxed{{ \large \sf f(-3)=-6}}}$

Therefore, the result of this expression is f(-3)=-6. ✅
