Answer 1

$f(x)= x^{2} -2x+2\\\\\\ a)f(-3)\to (-3)^{2} -2*(-3)+2\to 9+6+2\to 17\\\\\\\\b)f(-1)\to (-1)^{2} -2*(-1)+2\to 1+2+2\to 5\\\\\\\\ c)f(0)\to 0^{2} -2*0+2\to 0-0+2\to 2\\\\\\\\ d)f( \frac{2}{3} )\to ( \frac{2}{3})^{2} -2*( \frac{2}{3})+2\to \frac{4}{9}- \frac{4}{3}+2\to mmc=9\to\\4-12+18\to -12+22\to 10\\\\\\\\ e)f( \sqrt{2} )\to (\sqrt{2})^{2} -2*\sqrt{2}+2\to (\sqrt{4}) -2\sqrt{2}+2\to 2-2\sqrt{2}+2\to \\4-2\sqrt{2}\to 2(2- \sqrt{2} )$
