The given functions of <em>f </em>and <em>g</em>, where;
,
gives the domain of the functions as the option;
a. All non zero real numbers
<h3>How can the domain of the functions be found?</h3>
The given functions are presented as follows;


The given functions have <em>x²</em> as the denominator, therefore;
The domain of the functions are the possible x-values, which gives;
x² = (-x)² = Positive number
At <em>x </em>= 0, we have;


The domain is therefore;
a. All non zero real numbers

To find the slope, you find the change in y-values over the change in x-values.
Your first point is: (5,-3)
Your second point is (8, -5)
Your x-values are: 5 and 8
Your y-values are -3 and -5
The equation to find slope is: slope = (y2-y1)/(x2-x1)
- The 2s and 1s indicate which point the values belong to, it makes sure that you align the right x-value with its correct y-value. It doesn't matter which point you assign as 1 or 2, as long as the values match
- So, x-value 5 will match with y-value -3, and x-value 8 will match with y-value -5
Now you plug in out values :
slope = (y2-y1)/(x2-x1)
slope = (-5-(-3))/(8-5)
slope = (-2)/(3)
slope = -2/3
Answer:
20
400 is 20 square= 20*20
so 20 students in each row
Correct! That statement is completely accurate!
