restrict the domains of quadratic functions and absolute value functions, because these functions are

functions. For instance, the quadratic function f(x) = x^2 pairs both −2 and 2 with 4, and the absolute value function f(x) = |x| pairs both −2 and 2 with 2.
Linear functions (excluding constant functions) and exponential functions are

functions, so their domains

to be restricted.
_________________
An absolute value function, without domain restriction, has an inverse that is NOT a function.
In order to guarantee that the inverse must also be a function, we need to restrict the domain of the absolute value function to make it a one-to-one function.

Answer:
X=40°
X=30°
X=50°
Step-by-step explanation:
Let our unknown angles be denoted by 
Part I
We are given the sum of the angles as 70°, the known as 30° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=70°-30°=40°
Hence X= 40°
Part II
We are given the sum of the angles as 70°, the known as 40° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=70°-40°=30°
Hence X= 30°
Part III
We are given the sum of the angles as 80°, the known as 30° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=80°-30°=50°
Hence X= 50°
The correct answer to the above question is 3n^3/5m^2, i.e., the third option
Answer: x ≓ 6.899067609
Step-by-step explanation:
Easy because:
(2 • (x3)) - 11x2) - 18x) - 9 = 0
(2x3 - 11x2) - 18x) - 9 = 0
2x3 - 11x2 - 18x - 9 = 0
2x3-11x2-18x-9 = 0
F(x) = 2x3 - 11x2 - 18x - 9
At x= 6.00 F(x) is equal to -81.00
At x= 7.00 F(x) is equal to 12.00 F( 6.899067609 ) is -0.000000436
