Step-by-step explanation:
Given
Required
Determine if the function is quadratic
Start by representing the function as an x-y table
x:- 5 || 7 || 9 || 11
y:- 7 || 11 || 14 || 18
Next; Calculate the difference between the values of y
<em>The resulting difference are: 4 || 3 || 4</em>
Next; Calculate the difference between the difference of values of y
<em>The resulting difference are: -1 || 1</em>
<em>For the function to be quadratic, the above difference must be the same and since they are not, then the function does not represent a quadratic function.</em>
<em>Option D answers the question</em>
2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old
Soo....
Multiply that by two to get Kim's age
12•2=24 Kim is 24 years old.
