We are given expression: 
.
Tyna simplified the given expression to 
.
Explanation: In order to simplify , Tyna need to simplify rational expression 
.
On dividing top and bottom by 3, we get 
.
Which Tyna got correct.
Now she need to simplify 
.
<em>On applying quotient rule of exponents, we need to subtract the exponents of x's.</em>
So, it would be 
.
<h3>So, the final answer should be
.</h3><h3>Therefore, Tyan forgot to add exponent to x.</h3><h3>The exponent of x should be 5.</h3>
Simplifying, Dividing, and Evaluating....the answer is 2.
Now, if you want to Find the Domain (unlikely, but still possible), that's another answer.
Answer:
the student messed up at the point of adding 5 to I5, they subtracted instead and got 2x=I0 which would mean x=5. when instead they should've added 5 and got 2x=20 and got x=I0
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units left
f(x - n) - shift the graph n units right
-----------------------------------------------------------------
g(x) = 4x² - 16
Shift 9 units right and 1 unit down. Therfore:
g(x - 9) - 1 = 4(x - 9)² - 16 - 1 = 4(x - 9)² - 17
<h3>Answer: A. h(x) = 4(x - 9)² - 17</h3>
