A) approx = 1-8x
b) f(x) -8(1-x)^-1 approx = -8(1+x) = -8 - 8x
because 1/x = x^-1...
c) f(x) = (1+x)^-1/2 approx = 1- 1/2x
d) f(x) = (4+x^2)^1/2 approx = 4 + 1/2x^2
e) f(x) = (6+3x)^1/3 approx = 6+x
Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
