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|
Answer: 7.08
Reasoning: 49.56 divided by 7 is 7.08
Lets say groups = g
3 groups of 6 is
3(g) =6
3g/3 = 6/3
g = 2
there are 2 in each group
hope this helps
The estimate of 3630 is 4000. because the hundreds place is higher than 5, so you would go a number higher
