3(x-4)>= 5x+2
Distributing 3 on x-4
3(x)-3(4)>=5x+2
3x-12>=5x+2
Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides
-2x >=14
Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is
x<=-7
So, that takes lots of algebra, and I can't show it on this, because there are lots of symbols, so... ill try to figure out the functions for that.
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.
