wyznacz wartość funkcji f(x)= -x^2 -4x +1 dla x= 3pierwiastki z 2 -2
x= 3√2-2y=-(3√2-2)²-4(3√2-2)+1y=-(18-12√2+4)-12√2+8+1y=-18+12√2-4-12√2+8+1y=-13
f(x)= -x^2 -4x +1 dla x= 3√2 -2
f(x)= -x² - 4x +1
f(x) = -(3√2 - 2)² - 4(3√2 - 2) + 1
f(x) = -[ (3√2)² - 2 * 3√2 * 2 + 2²] - 12√2 + 8 + 1
f(x) = -(18 - 12√2 + 4) - 12√2 + 9
f(x) = -18 + 12√2 - 4 - 12√2 + 9
f(x) = -13 ------ odpowiedx
