Answer:

Hence, option A is correct.

i.e. the range is {-2,2,5,7}

Step-by-step explanation:

" The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain "

We are given a information about the function f(x) as:

{(8, 2), (6, 5), (4, 7), (11, −2)}

Where these ordered pair represent the function f(x).

i.e. the set is (x,f(x)).

Now clearly based on the given information we could see that the range of the function f(x) is:

{2,5,7,-2}

SOLUTION

From the given value

Since

$\sin u=\frac{7}{25}$

Then using trigonometrical ratios it follows

$\cos u=\frac{24}{25}$

Using hal -ngle it folows

$\begin{gathered} sin(\frac{u}{2})=\sqrt{\frac{1-\frac{24}{25}}{2}} \\ s\imaginaryI n(\frac{u}{2})=\sqrt{\frac{1}{50}} \end{gathered}$

Also

$\begin{gathered} cos(\frac{u}{2})=\pm\sqrt{\frac{1+\frac{24}{25}}{2}} \\ cos(\frac{u}{2})=\sqrt{\frac{49}{50}} \\ cos(\frac{u}{2})=7\sqrt{\frac{1}{50}} \end{gathered}$

Finally?

$\begin{gathered} \tan(\frac{u}{2})=\pm\sqrt{\frac{1-\frac{24}{25}}{1+\frac{24}{25}}} \\ \tan(\frac{u}{2})=\sqrt{\frac{1}{49}} \\ \tan(\frac{u}{2})=\frac{1}{7} \end{gathered}$
