Answer 1

4)

17.-

f(x) = x^2 - 6

f(-3) = (-3)^2 - 6 = 3

f(3) = (3)^2 - 6 = 3

f(0) = (0)^2 - 6 = -6

f(1/2) = (1/2)^2 - 6 = -23/4

f(10) = (10)^2 - 6 = 94

18.-

f(x) = x^3 + 2x

f(-2) = (-2)^3 + 2(-2) = -12

f(1) = (1)^3 + 2(1) = 3

f(0) = (0)^3 + 2(0) = 0

f(1/3) = (1/3)^3 + 2(1/3) = 19/27

f(.2) = (.2)^3 + 2(.2) = .408

5)

a) C(10) = 1500 + 3(10) +.02(10)^2 + .0001(10)^3 = 1532.1

C(100) = 1500 + 3(100) + .02(100)^2 + .0001(100)^3 = 2100

b) Representa el costo de la tela dependiendo las yardas.

6)

a) S(r) = 4πr^2

S(2) = 4π(2)^2 = 16π

S(3) = 4π(3)^2 = 36π

b) Representa el área superficial respecto del radio.
