Given the function f(x)=0.3(4)x
what is the value of
f−1(6)

a. 0.360
b. 1.242
c. 2.161
d. 2.312

Answers

Answer 1
Answer: For this case we have the following function:
 f (x) = 0.3 (4) ^ x
 Rewriting we have:
 y = 0.3 (4) ^ x
 From here, we clear the value of x:
 (4) ^ x = y / 0.3log4 ((4) ^ x) = log4 (y / 0.3)
 Rewriting we have:
 x = log4 (y / 0.3)
 Therefore, the inverse function is given by:
 f ^ {-1} (x) = log4 (x / 0.3)
 For x = 6 we have:
 f ^ {-1} (6) = log4 (6/0.3)f ^ {-1} (6) = 2.161
 Answer:
 is the value of f^-1(6) is:
 c. 2.161
Answer 2
Answer:

f(x)=0.3(4)^x

f^-1(x) = ?

x = 0.3(4)^y

4^y = x/0.3

4^y = 6/0.3

4^y = 20

y = 2.161

What is the product of a subtraction equation called?

Answer:

The "difference".

Step-by-step explanation:

In the equation 7-5=2, 2 is the "difference" between those numbers. Be careful when calling it a product though, because a product is the result of a multiplication equation!

One half of a number is 3 more than one-sixth the same number. What is the number?

Answers

1/2 of a number(1/2 times x) is (=) 3 more than (3+) 1/6 the same number (1/6 times x)

1/2x=3+1/6x
x/2=3+x/6
subtract x/6 from both sdies
x/2-x/6=3
x/2-x/6
x/2 times 3/3=3x/6
3x/6-x/6=2x/6=x/3
x/3=3
multiply both sides by 3
x=9

9 is the number
(x)/(2) = (x)/(6) + 3

3x= x+18

2x=18

x=9
