domain of f(x)=(2x+1)/(x^2-49)

Solution

domain

f (x) = \frac{2 x + 1}{x ^{2} - 49}

Solution

x < - 7 or - 7 < x < 7 or x > 7

+1

Solution steps

Find undefined (singularity) points:

x = 7, x = - 7

The function domain

x < - 7 or - 7 < x < 7 or x > 7

Popular Examples

inverse of e^{4sqrt(x)}inverse

e^{4 x}

critical f(x)=ln(x-3)critical points

f (x) = ln (x - 3)

range of-x^2+4x-4 range

- x^{2} + 4 x - 4

intercepts of f(x)=3x-y=9 intercepts

f (x) = 3 x - y = 9
