Given 3x^2+x-4/x-1 what are the domain and range
1 answer:
Answer:
- doman: x ≠ 1
- range: y ≠ 7
Step-by-step explanation:
The domain is the horizontal extent of the graph, the set of x-values for which the function is defined. The range is the vertical extent of the graph, the set of y-values defined by the function.
<h3>Simplified</h3>The given function is undefined where its denominator is zero, at x=1. Everywhere else, it can be simplified to ...
The simplified function (3x+4) is defined for all values of x except x=1. The simplest description is ...
x ≠ 1
In interval notation, this is ...
(-∞, 1) ∪ (1, ∞)
<h3>Range</h3>
The simplified function is capable of producing all values of y except the one corresponding to x=1: 3(1)+4 = 7. The simplest description is ...
y ≠ 7
In interval notation, this is ...
(-∞, 7) ∪ (7, ∞)

Answer:
D.
Step-by-step explanation:
Consider the set
This set consists of four ordered pairs.
The first numbers in these pairs are These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and
