Find the smallest integer n for an o(xn) estimate of order of the function f(x)
f(x) = (x3+ x2 + 5)(x4 - 3x2)/[(2x2 + 2x - 3)(4x2 + 7)];

Answer with explanation:

The largest degree of numerator is 7 , while the largest degree of denominator is 4.So, as we know

→So, order of the function is the highest degree in the function raised to power.Highest degree is 3,when you will reduce the function in Expression form.

So, Degree=3

Order=1

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
