Question

Find the range of value of the reciprocal of x when x belongs to [-3,5]

Answer 1

Answer:

-5 and 3 please mark me brainly and follow me please

Answer 2

The range of reciprocal of x is (-∞, -1/3] ∪ [1/5, ∞)

Step-by-step explanation:

Reciprocal of x is 1/x

Given

$-3\le x\le 5$

Case I

If $-3\le x<0$

Then

$-\frac{1}{3}\ge \frac{1}{x}>\infty$

or, $\infty<\frac{1}{x}<-\frac{1}{3}$

Case II

If $0< x\le 5$

Then

$\infty>\frac{1}{x}\ge\frac{1}{5}$

or, $\frac{1}{5}\le \frac{1}{x}\le \infty$

Case III

At x = 0, 1/x is not defined

Therefore, the range of reciprocal of x is

x ∈ (-∞, -1/3] ∪ [1/5, ∞)
