domain of f(x)= 1/(x^2+1)

Solution

domain

f (x) = \frac{1}{x ^{2} + 1}

Solution

- \infty < x < \infty

+1

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

(5.6), (1.3)

domain of f(x)=ln(x^2-12x)domain

f (x) = ln (x^{2} - 12 x)

critical f(x)=x^4-12x^3 critical points

f (x) = x^{4} - 12 x^{3}

domain of f(x)=(cos(x))/(1-sin(x))domain

f (x) = \frac{cos ( x )}{1 - sin ( x )}

monotone 2x^2-3x+4 monotone intervals

2 x^{2} - 3 x + 4
