For the function f (x) = 3 (x + 7), find -1().
AlekseyPX

Given:

The function is f(x)=3(x+7)^{\frac{1}{4}}.

To find:

The function f^{-1}(x).

Solution:

We have,

f(x)=3(x+7)^{\frac{1}{4}}

Substitute f(x)=y.

y=3(x+7)^{\frac{1}{4}}

Interchange x and y.

x=3(y+7)^{\frac{1}{4}}

Divide both sides by 3.

\dfrac{x}{3}=(y+7)^{\frac{1}{4}}

Taking power 4 on both sides.

\left(\dfrac{x}{3}\right)^4=y+7

Subtract 7 from both sides.

\left(\dfrac{x}{3}\right)^4-7=y

y=\left(\dfrac{x}{3}\right)^4-7

Substitute y=f^{-1}(x).

f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7

Therefore, the correct option is C.

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she wil
Harrizon [31]

Answer:

12 pounds

Step-by-step explanation:

We know that the candy costs $4 per pound

We also know that he will only spend up to $48

We can represent this as an equation:

4x = 48

Where as x = number of pounds

Solve the equation to find how many pounds he can buy.

4x = 48

Divide both sides by 4

x = 12

This means that Kareem can buy 12 pounds

Help with 7 and 8 please <br> ASAP !!! Thanks
lukranit [14]

7) 52h because that's how you'd find the distance traveled if there was a number instead of a variable.(d=st)

8)525+3w because you have to add his original total to the amount of cds he will get and if he gets 3 every week that's 3w and then you add them to get the new total.
