Answer:
It is not a function.
Step-by-step explanation:
If the x input or the y output in the given equation have no meaning or does not have any sense, then it will not form a function. We need to see if there are two of the x - intercept which are same. Then the graph will be a straight vertical line. Also the slope of the function cannot be determined.
Say there are two fractions, 1/3 and 3/7. first, find a common denominator (21). Multiply each number like this: 1/3 * 7/7= 7/21 and 3/7 * 3/3=9/21. Now, just compare. 7/21 is less than 9/21. :)
25 - 6x - 12 - 2x
Combine like terms:
-6x - 2x = -8x
25 - 12 = 13
So we have:
-8x + 13
