domain of f(x)= 7/x+2

Solution

domain

f (x) = \frac{7}{x} + 2

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

inverse of f(x)= 4/x-4 inverse

f (x) = \frac{4}{x} - 4

extreme f(x)=2x^3-6x extreme points

f (x) = 2 x^{3} - 6 x

symmetry (2x^2)/(x^2-1)symmetry

\frac{2 x ^{2}}{x ^{2} - 1}

shift f(x)=2sin(x-pi/3)shift

f (x) = 2 sin (x - \frac{π}{3})

slope ofintercept 6x+5y=5 slope intercept

6 x + 5 y = 5
