The x-coordinate of the given endpoint will be "
".
According to the question,
The end points are:
Distance,
As we know,
The distance formula,
→ 
By substituting the values, we get
→ 
→ 
→ 
→ 
→ 
→
Thus the above answer is right.

Answer:
See attachment
Step-by-step explanation:
To see clearly the graph that represents

we rewrite in vertex form to get;

This is a vertical parabola with vertex at (-1.5,-0.25) and opens upwards.
The required graph is shown in the attachment.
Answer:
No
Step-by-step explanation:
An extraneous solution is a root of a transformed equation which is not a root of the original equation because it was not included in the domain of the original equation.
Ahmed is solving
for x.
His steps were:
![\begin{aligned}2\sqrt[3]{x-7}&=-8\\ \sqrt[3]{x-7}&=-4\\ \left(\sqrt[3]{x-7}\right)^3&=(-4)^3\\ x-7&=-64 \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D2%5Csqrt%5B3%5D%7Bx-7%7D%26%3D-8%5C%5C%20%20%5Csqrt%5B3%5D%7Bx-7%7D%26%3D-4%5C%5C%20%20%5Cleft%28%5Csqrt%5B3%5D%7Bx-7%7D%5Cright%29%5E3%26%3D%28-4%29%5E3%5C%5C%20%20x-7%26%3D-64%20%5Cend%7Baligned%7D)
Since cube roots <u>do not give two solutions when solved</u>, it is <u>not necessary </u>to check his answers for extraneous solutions.
