F (x) = -3 + 7. Find the inverse of f(x) and its domain.

Mathematics

iragen [17]3 years ago

Note: Your function is missing some information. It seems your function is

f\left(x\right)=\frac{-3}{x}+7.

So, I am solving the question based on the function f\left(x\right)=\frac{-3}{x}+7,  because it would still solve your query.

Answer:

Please see the explanation.

Step-by-step explanation:

Given the function

f\left(x\right)=\frac{-3}{x}+7

A function g is the inverse of a function f for y = f(x), x=g(y)

y=\frac{-3}{x}+7

Replace x with y

x=\frac{-3}{y}+7

solve for y

y=-\frac{3}{x-7}

so the inverse of f\left(x\right)=\frac{-3}{x}+7 will be:

f^{-1}\:\left(x\right)=-\frac{3}{x-7}

Finding the domain of f^{-1}\:\left(x\right)=-\frac{3}{x-7}

As we know that domain is the set of the possible input values where the function is defined.

so the function domain must be: x7

Therefore,

\mathrm{Domain\:of\:}\:-\frac{3}{x-7}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:7\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}

What can you say about the continuous function that generated the following table of values?
scoundrel [369]

Option C. The function that has the table here has  exactly one x-intercept.

<h3>How to find the intercept</h3>

As the signs of the functions are changing, we can see that there is a crossing to the x axis.

This tells us that the zero value that we see is the x intercept and there is no other x intercept in the question.

A new health drink has 130​% of the recommended daily allowance​ (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg.
Anika [276]
Answer:
58.5 mg

Step-by-step explanation:

Drink: 130% of RDA of vitamin X
RDA vitamin X = 45mg
130% of 45 = mg in the drink
130% = 130/100 = 1.3
130% of 45 = 1.3*45 = 58.5

So, this new drink has 58.5 mg of vitamin
