Answer:
x > -
Step-by-step explanation:
Given
10 - 2(3x + 4) < 11 ← distribute and simplify left side
10 - 6x - 8 < 11
2 - 6x < 11 ( subtract 2 from both sides )
- 6x < 9
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
x > ⇒ x > -
Option B shows the correct representation of the given function.
Option B is "–6 is not in the domain of f(x) but is in the range of f(x)."
<h2 /><h2>Function</h2>A Function can be defined as an expression that defines a relationship between one independent variable with another dependent variable.
The given function is .
Let us consider that x-7 is greater than or equal to 0. Then,
The value of x greater than or equal to 7 shows the domain function. Hence the domain function is .
Now if x-7 is greater than or equal to 0 then,
If the above equation is multiplied by -2 then,
Now add +1 in both sides of the above equation, we get,
.
The above expression of the function represents that the given function is in the range of .
Hence we can conclude that option B represents the correct expression that is "–6 is not in the domain of f(x) but is in the range of f(x)".
