Which of the following could be the graph of this equation?
Anna35 [415]

Answer: OPTION C.

Step-by-step explanation:

Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.

For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).

Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.

Therefore, you need to search the option that shown the graph wich contains the point (1,-3).

Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).

This is the graph of the option C.

Ahmed is solving the following equation for xxx.
Dennis_Churaev [7]

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 2\sqrt[3]{x-7}+11=3 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}

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.
