Answer:
take a picture of the problem
Answer:
Domain: x=(0,∞)
Range: f(x)=(-∞,∞)
Step-by-step explanation:
For the domain:
The square root of a number is defined in real numbers only for positive numbers.
For the range:
The square root of a number could be positive or negative with any restriction. For example,
could be 5 or -5.
Proved
Explanation:
To prove x^m · x^n=x^m+n, let's assign numbers to x, m and n
let x = 2
m = 3, n = 4
x^m · x^n = 2^3 . 2^4
x^m+n = 2^(3+4)
Solve each of the above seperately and comparew the answer:



This expression x^m · x^n=x^m+n has been proved to be equal
B because 13 x 13 = 169
3.14 x 169 = 530.7
Hello
<span>x² + y² - x - 2y - 11/4 = 0
(x²-x) +(y²-2y)-11/4 = 0
(x-0.5x)²-(1/2)² + (y-1)² -1² -11/4=0
(x-0.5)² +(y-1)² = (1/4)+1+(11/4)
= </span> (1/4)+(4/4)+(11/4)
(x-0.5)² +(y-1)² =4²
