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
For this case we have the following functions:

We must find the following sum of functions:
(f + g) (x)
By definition we have to:

So, we have to:

Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
