So far the only true statement I see is that function f is increasing whilst function g is decreasing.
I cannot say yes to the first one as there is a lack of x-intercepts.
Past the interval of 0,2, there are no changes in the line of function g as it remains the same despite the increase in y. Function f on the other hand has a rate of change.
The y-intercepts are the same (positive 2) so the third statement is out.

<h2>Explanation:</h2><h2></h2>
Here we need to set a system of two linear equations in two variables. So:
- <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>
Let be those digits, then:
- <em>If 9 is added to a number then both the digits become equal. find the number:</em>
<em />
<em /><em />
<em />
But from eq 1:
Substituting y into the expression 1:
The x-value will be found by hit and trial, so:
- Let x = 1:
We have to reject this solution because digits are different.
- Let x = 2:
We have to reject this solution because digits are different.
- Let x = 3:
<em>Then this is a two digit number formed by two equal digits. </em>
Finally, the number is:
