Step-by-step explanation:

$\bf 3\sqrt{8} -\sqrt{50} +2\sqrt{18} =$

$\bf 3\sqrt{2^{3}} -\sqrt{2\cdot5^{2}} +2\sqrt{2\cdot3^{2}} =$

$\bf 3\cdot 2\sqrt{2} -5\sqrt{2} +2\cdot3\sqrt{2} =$

$\bf 6\sqrt{2} -5\sqrt{2} +6\sqrt{2} =$

$\bf 12\sqrt{2} -5\sqrt{2} =\green{\underline{~7\sqrt{2}~}}$

__________________

$\bf \sqrt{12} -\sqrt{27} +2\sqrt{75} =$

$\bf \sqrt{2^{2}\cdot3} -\sqrt{3^{3}} +2\sqrt{3\cdot5^{2}} =$

$\bf 2\sqrt{3} -3\sqrt{3} +2\cdot5\sqrt{3} =$

$\bf 2\sqrt{3} -3\sqrt{3} +10\sqrt{3} =$

$\bf 12\sqrt{3} -3\sqrt{3}=\blue{\underline{~9\sqrt{3}~}}$

Hello :

Answer :C

Because :

f ( - 4 ) = 4(-4)+9 = -16 +9 = -7

f ( - 2 ) = 4(-2)+9 = - 8 +9 = 1

f (0 ) = 4(0)+9 = 9

f ( 2 ) = 4(2)+9 = 17
