f(x) = x² - 5x + 7
=> x=2
f(2) = (2)²-5(2)+7
=> 4-10+7
= 14
f(x) = x² - 5x + 7
x = -1
f(-1) = (-1)²-5(-1)+7
= 1 +5+7
= 13
f(x) = x² - 5x + 7
f(1/3) = (1/3)²-5(1/3)+7
= 1/9-5/15+7
= 1-1+7/3
= 16/3
=> x=2
f(2) = (2)²-5(2)+7
=> 4-10+7
= 14
f(x) = x² - 5x + 7
x = -1
f(-1) = (-1)²-5(-1)+7
= 1 +5+7
= 13
f(x) = x² - 5x + 7
f(1/3) = (1/3)²-5(1/3)+7
= 1/9-5/15+7
= 1-1+7/3
= 16/3
