domain of f(x)=(x+7)/(x^2-14x+49)

domain

f (x) = \frac{x + 7}{x ^{2} - 14 x + 49}

x < 7 or x > 7

Solution steps

Find undefined (singularity) points:

x = 7

The function domain

x < 7 or x > 7

9 x - 12 y = - 19

f (x) = x^{2} e^{x} - 4

3 x + y = 8

f (x) = \frac{- x ^{2}}{x ^{2} - 2 x + 8}

f (x) = \frac{( 2 x + 4 )}{3}

What is the domain of f(x)=(x+7)/(x^2-14x+49) ?
The domain of f(x)=(x+7)/(x^2-14x+49) is x<7\lor x>7
