Answer:
ADD 3/2
Step-by-step explanation:
-1/2 + 3/2 = 1
1+3/2= 1/1+3/2 = 2/2 + 3/2 =5/2
5/2 +3/2 = 8/2 = 4
4+3/2 = 8/2 +3/2 = 11/2
11/2 +3/2 =14/2 =7

Answer:
5. f(x) = -2x² + 3x
f(-3) = -2(-3)² + 3(-3) = -27
f(2) = -2(2)² + 3(2) = -2
f(-a) = -2(-a)² + 3(-a) = -2a² - 3a
-f(a) = -[-2a² + 3a] = 2a² - 3a
f(a + h) = -2(a + h)² + 3(a + h) = -2(a² + 2ah + h²) + 3a + 3h = -2a² - 4ah - 2h² + 3a + 3h
6. f(x) = 2|3x - 1|
f(-3) = 2|3(-3) - 1| = 2*10 = 20
f(2) = 2|3(2) - 1| = 2*5 = 10
f(-a) = 2|3(-a) - 1| = 2|-3a - 1|
-f(a) = -(2|3a - 1|) = -2|3a - 1|
f(a + h) = 2|3(a + h) - 1| = 2|3a + 3h - 1|
