Matematika jika f(x)=x2-4x+5 dengan domain -1≤×≤4 maka range dari f(x) adalah ​

jika f(x)=x2-4x+5 dengan domain -1≤×≤4 maka range dari f(x) adalah ​

Penjelasan dengan langkah-langkah:

f(x) = x² - 4x + 5

f(-1) = (-1)² - 4(-1) + 5

= 1 + 4 + 5

= 10

f(0) = 0² - 4(0) + 5

= 5

f(1) = 1² - 4(1) + 5

= -3 + 5

= 2

f(2) = 2² - 4(2) + 5

= 4 - 8 + 5

= 1

f(3) = 3² - 4(3) + 5

= 9 - 12 + 5

= 2

f(4) = 4² - 4(4) + 5

= 16 - 16 + 5

= 5

maka range = -1 ≤ y ≤ 10 → B
