What is the range and domain of the function : y= sqrt(x) -5 ... Can you please explain? Thanks btw the square root is only over the x
Answers
Domain of - 5 : x ≥ 25 .
Range of √x - 5 : y ≥ -5 .
Given,
f(x) = √x - 5
Here,
To find the domain,
√x - 5 ≥ 0
√x ≥ 5
Squaring both sides ,
x ≥ 25 .
Thus domain of √x - 5 is x ≥ 25 .
Range of √x - 5,
To define the range of the function the value of x can not be negative as it will make the function complex .
So,
Range will be ,
y ≥ -5 .

for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.

The product that is equivalent to the given expression is: A. (5x-4)(5x+4)..
What are Equivalent Expressions?
Equivalent expressions are expressions that have equal value when simplified.
(5x-4)(5x+4) is equivalent to 25x² – 16 because if we expand we would have:
5x(5x+4) -4(5x+4)
5x² + 20x - 20x - 16
Add like terms
25x² – 16
Therefore, the product that is equivalent to 25x² – 16 is: A. (5x-4)(5x+4).

The number of individual eggs that were sold is (a) 36,000
How many individual eggs were sold?
From the question, we have the following parameters that can be used in our computation:
Eggs = 3000 dozen
By defintiion
1 dozen = 12
substitute the known values in the above equation, so, we have the following representation
Eggs = 3000 * 12
Evaluate
Eggs = 36000
Hence, a total of (a) 36000 individual eggs were sold
