The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.
First you have to subtract 3x and then divide everything by -4 to get y=3/4x-7
In point for (2,7) and in Equation form x=2 y=7
You keep the same sign. So:-
4 + 4 = 8 and
--4 + -4 = -8
Answer:
a) -27 a³ b⁶
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given ( -3 ab² )³
By using (ab )ⁿ = aⁿ bⁿ
( -3 ab² )³ = (-3)³ a³ (b²)³
Again , using formula 
= -27 a³ b⁶
