Answer:
x = 7
Step-by-step explanation:
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 21 ÷ 3
x = 7

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 )![.^x](https://tex.z-dn.net/?f=.%5Ex)
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:
Step-by-step explanation:
<span>When you calculate results that are aiming for known values,
the </span>percent error<span> formula
is useful tool for determining the precision of your calculations. The formula
is given by: The experimental value is your calculated value, and the
theoretical value is your known value.</span>
% error = | ( experimental – theoretical) / theoretical | *
100
% error = | (44 – 45.5) /45.5| * 100
<span>% error = 3.30 %</span>
