Answer:
Step-by-step explanation:
for Which of the functions represents a linear function? Explain your reasoning, then determine the rate of change for that function over the interval 2≤x≤4.
For a linear function, the rate of change is represented by the parameter m in the slope-intercept form for a line: y=mx+b, and is visible in a table or on a graph.
Remark
This is like using the distributive principle only you are going backwards. Instead of trying to remove brackets, you are trying to create them.
Solution
Since you want to take - 6 outside the brackets you should divide both terms by - 6
<em><u>- 18a</u></em>: - 18a/- 6 = 3a which is left inside the brackets.
<em><u>-30:</u></em> - 30/-6 = 5
- 6(3a + 5)
Answer
-6(3a + 5)
