The correct answer is option A which is x > 0 The domain of the given function will be greater than zero.
<h3>
What is a function?</h3>
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function:-
F(x) = 3 - ( 1 )
The function will give results for all the values greater than zero. As we put the input values in the function we will get the output.
At x = 1 F(x) = 3 - ( 1 )¹ = 3 - 1 = 2
At x = 2 F (x ) = 3 - ( 2 )² = 3 - 1 = -1
Therefore the correct answer is option A which is x > 0 The domain of the given function will be greater than zero.

Answer:
Option C is correct.
Step-by-step explanation:
-x+3y=2
4x-2y=22
In matrix form is represented as:
AX=B
|A| = (-1)(-2)-(3)(4)
|A| = 2-12
|A| = -10
Adj A =
A^-1 = -1/10
A^-1 = 1/10
X= A^-1 B
X = 1/10
X=1/10
So, x = 7 and y =3
Hence Option C is correct.
Answer:
It is D. (x + 1)^2 + (y - 3)^2 = 16.
Step-by-step explanation:
The general equation of a circle is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and the radius is r.
So substituting the given values the required equation is:
(x + 1)^2 + (y - 3)^2 = 4^2.
Answer:
Step-by-step explanation:
Answer :
m = 13.4/4.65
Step by step :
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
7.8 + 2.75m + 0.8 = -6.4m + 4.5m - 4.8
2.75m + 6.4m - 4.5m = -7.8 - 0.8 - 4.8
4.65m = 13.4
m = 13.4/4.65
