The function h(x) = (x^2 - 2) / x has no points of inflection because its second derivative, h''(x) = -4 / x^3, has no real solutions.
To find the points of inflection for a function h(x), you need to follow these steps:
Find the second derivative, h''(x).
Set h''(x) = 0 and solve for x.
Find the corresponding y values for the x values obtained in step 2.
Let's find the points of inflection for the given function h(x) = (x^2 - 2) / x.
Find the first derivative h'(x):
h'(x) = ((x * (2x) - (x^2 - 2) * 1) / x^2 = (2x^2 - x^2 + 2) / x^2 = (x^2 + 2) / x^2
Find the second derivative h''(x):
h''(x) = ((x^2 * 2 - (x^2 + 2) * 2x) / x^4 = (2x^2 - 2x^2 - 4x) / x^4 = -4x / x^4 = -4 / x^3
Set h''(x) = 0 and solve for x:
-4 / x^3 = 0
This equation has no solution because the numerator is a constant (-4) and cannot be equal to zero.
So, the given function h(x) = (x^2 - 2) / x does not have any points of inflection.
