domain of f(x)= 2/((\frac{2){x-7})-7}

domain

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

x < 7 or 7 < x < \frac{51}{7} or x > \frac{51}{7}

Interval Notation

(- \infty, 7) \cup (7, \frac{51}{7}) \cup (\frac{51}{7}, \infty)

Solution steps

Find undefined (singularity) points:

x = \frac{51}{7}, x = 7

The function domain

x < 7 or 7 < x < \frac{51}{7} or x > \frac{51}{7}

f (x) = \frac{x}{2 x - ∣ x ∣}

f (x) = x^{2} + 8 x - 9

f (x) = \frac{6 x}{x ^{2} - 14 x + 45}

(x - 9) (x^{2} - 18 x - 162)

2 x^{2} + 5 x - 12

What is the domain of f(x)= 2/((\frac{2){x-7})-7} ?
The domain of f(x)= 2/((\frac{2){x-7})-7} is x<7\lor 7<x< 51/7 \lor x> 51/7
