Question

mohon bantuannya kakak, tugas saya numpuk:)​

Answer 1

Penjelasan dengan langkah-langkah:

{x| -1 ≤ x ≤ 4 ,xER} = -1, 0, 1, 2, 3, 4

f(x) = x² - 2x - 3

.

f(-1) = (-1)² - 2(-1) - 3 = 0

f(0) = 0² - 2(0) - 3 = -3

f(1) = 1² - 2(1) - 3 = -4

f(2) = 2² - 2(2) - 3 = -3

f(3) = 3² - 2(3) - 3 = 0

f(4) = 4² - 2(4) - 3 = 5

.

Range = -4, -3, 0, 5 = {y| -4 ≤ y ≤ 5, yER}
