Answer:
-6 is not in the domain of f(x) but in the range of f(x)
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
The given function is:
f(x) = -2 + 1
To make f(x) is defined, the value inside the square root must be ≥0
<=> x - 7 ≥0
<=> x ≥7
=> -6 is not in the domain of f(x)
How about in the range of f(x)? We can test it by using this ex:
f(x) = -2 + 1 = -6
<=> -2 = -7
<=> = 7/2
<=> x - 7 = 49/4
<=> x = 77/4 ≥7
So -6 is in the domain of f(x)
–6 is not in the domain of f(x) but is in the range of f(x)
Answer:
5/9 is an example of rational number.
Step-by-step explanation:
as the definition of rational number is the number in the form of p/q but the value of denominator q should not be equal to 0. Every integer is a rational number.
Answer:
27 inches
Step-by-step explanation:
We can use a ratio to solve
10 15
---- = ----
18 x
Using cross products
10x = 15*18
10x=270
Divide each side by 10
10x/10 = 270/10
x = 27

Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 7 - (- 3) = 17 - 7 = 27 - 17 = 10
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 10, thus
= - 3 + 10(n - 1) = - 3 + 10n - 10 = 10n - 13 ← explicit formula
The recursive formula allows a term to be found by adding d to the previous term, thus
= + 10 ← recursive formula
