Answer: Second Option

$f (x)=\frac{2}{x}$ and $g(x)=\frac{2}{x}$

Step-by-step explanation:

If we have a function f(x) and its inverse function $f ^ {- 1} (x) = g (x)$

Then by definition:

$(fog) (x) = (gof) (x) = x$

Notice that the inverse of the function $f (x)=\frac{2}{x}$ is $f ^ {- 1}(x)=\frac{2}{x}$

then:

If $f (x)=\frac{2}{x}$ and $g(x)=\frac{2}{x}$

Then:

$(fog) (x) =\frac{2}{\frac{2}{x}}$

$(fog) (x) =\frac{2x}{2}$

$(fog) (x) =x$

The answer is the second option

3. A dealer altered his trade discount from 15% to 10%. By whatpercent was selling price altered?

BabaBlast [244]

Answer:

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.

Is the following expression true or false? Show your work.

SOVA2 [1]

Answer:

The expression is true.

Explanation:

$(x^2+8x+16)(x^2-8x+16)=(x+4)^2(x-4)^2=((x+4)(x-4))^2$

We know that (a +b)(a-b) = a²-b²

So we have ,

$((x+4)(x-4))^2=(x^2-4^2)^2=(x^2-16)^2$

Which is Right Hand Side given.

So, the expression is true.
