You need to take the whole function of g(x) and plug it into every single x within f(x). Bit tricky, so it just means we need to be careful. Alright, so this is the first set-up<span><span><span><span>−2x−7</span><span>x−1</span></span>−7</span><span><span><span>−2x−7</span><span>x−1</span></span>+2</span></span>So what You should do is make the top portion and the bottom portion all into one fraction. This means I need a common denominator. So to do this, I'll take x-1 as a common denominator and multiply it up into the numerator and the imaginary 1 denominator of -7 and 2. Doing this I have:<span><span><span>−2x−7−7(x−1)</span><span>x−1</span></span><span><span>−2x−7+2(x−1)</span><span>x−1</span></span></span>From here if I divide the top fraction and the bottom fraction, (x-1) will cancel out dueto me flipping the bottom fraction and multiplying. So that leaves me with:<span><span>−2x−7−7(x−1)</span><span>−2x−7+2(x−1)</span></span>Now if I multiply everything out and combine like terms I will have:<span><span><span>−2x−7−7x+7</span><span>−2x−7+2x−2</span></span>=<span><span>−9x</span><span>−9</span></span>=x</span>So that is the first part. We have to check both ways to confirm they are actually inverses of each other, though. Take a look at this part and see if you can make sense of what I did.
Answer:
The height of the prism is 7 unit
Step-by-step explanation:
Given as :
The volume of right triangle prism = v = 21 cubic unit
The length of one base = 
= 2 unit
The length of other base = 
= 3 unit
Let The height of the prism = h unit
<u>Now, According to question</u>
Volume of prism = 
× × × height
Or, v = × × × h
Or, 21 cubic unit = × 2 unit × 3 unit × h unit
Or, 21 = × 6 × h
Or, 21 = 3 × h
∴ h = 
i.e h = 7 unit
So,The height of the prism = h = 7 unit
Hence, The height of the prism is 7 unit Answer
