we get the following answers:
f(0) = -6
f(3) = -9
f(-2) = 6
Given the function is f(x) = x² ₋ 4x ₋ 6
we need to find for f(0):
f(0) = 0² ₋ 4(0) ₋ 6
f(0) = ₋6
f(3) = 3² ₋ 4(3) ₋ 6
f(3) = 9 ₋ 12 ₋ 6
f(3) = ₋9
f(₋2) = (₋2)² ₋ 4(₋2) ₋ 6
f(₋2) = 4 ₊ 8 ₋ 6
f(₋2) = 6
we need to prove f(1/2)f(7/2)
now, f(1/2) = (1/2)² ₋ 4(1/2) ₋ 6
f(1/2) = 1/4 ₋ 2 ₋ 6
f(1/2) = 1 ₋ 8 ₋ 24 / 4
f(1/2) = ₋31/4
f(7/2) = (7/2)² ₋ 4(7/2) ₋ 6
f(7/2) = 49/4 ₋ 14 ₋ 6
f(7/2) = 49 ₋ 56 ₋ 24 / 4
f(7/2) = ₋31/4
therefore, f(1/2) = f(7/2)
f(2₋h) = (2₋h)² ₋ 4(2₋h) ₋ 6
f(2₋h) = (4 ₊ h² ₋ 4h) ₋ 8 ₊ 4h ₋ 6
f(2₋h) = h² ₊ 4 ₋ 4h ₋ 8 ₊ 4h ₋ 6
f(2₋h) = h² ₋ 10
f(2₊h) = (2₊h)² ₋ 4(2₊h) ₋ 6
f(2₊h) = 4 ₊ h² ₊ 4h ₋ 8 ₋ 4h ₋ 6
f(2₊h) = h² ₋ 10
therefore, f(2₋h) = f(2₊h)
Hence proved.
