Answer:

The statement is false because f^{-1} (x) denotes the inverse of function f, whereas \frac{1}{f(x)} is the reciprocal values of f.

<em>(The first answer choice)</em>

Step-by-step explanation:

Well x usually represents y which is why x is in parentheses.

f^{-1}(x) is the inverse of f.

So f is the inverse of x.

The last number is usually what you divide x by.

So it would usually be f(x) over the first number that has the variable. The variable is being subtracted by the last number rather than being multiplied like in normal f(x).

I'd say that the statement is false because f^{-1}(x) is the inverse which means \frac{f(x)}{1}

The function that \frac{1}{f(x)} is describing would be reciprocal.

If you need further assistance don't be afraid to reach out. I hope this helps!

A tennis ball weighs about 57.6 grams. about how many apuntes would 12 tennis balls weigh?
Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

Step-by-step explanation:

The weight of each  tennis ball =  57.6 grams

So, the weight of 12 balls    =    12 x ( weight of 1 ball)

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams

Please Help! Will Give A Brainliest!!
Ray Of Light [21]
A) because when they are equal it means that their y has the same value, which means their intersection point.


B) You should take all integers from (-2, 2) which are: -2, -1, 0, 1, 2 and put them one by one in the example:
x = -2    
    y1 = 4^-(-2) = 4^2 = 16 
    y2 = 2^(-(-2) + 1) = 2^(2+1) = 2^3 = 8
y1 ≠ y2      =>      so x=-2 isn't our answer
-------------------------------------------------------
x = -1
    y1 = 4^-(-1) = 4^1 = 4 
    y2 = 2^(-(-1) + 1) = 2^(1+1) = 2^2 = 4
y1 = y2      =>       so our answer will be x = -1
-------------------------------------------------------
x = 0
    y1 = 4^-(0) = 4^0 = 1 
    y2 = 2^(-(0) + 1) = 2^(0+1) = 2^1 = 2
y1 ≠ y2      =>      so x=0 isn't our answer
--------------------------------------------------------------
x = 1 
    y1 = 4^-(1) = 4^(-1) = 1/4 
    y2 = 2^(-(1) + 1) = 2^(-1+1) = 2^0 = 1
y1 ≠ y2      =>      so x=1 isn't our answer
--------------------------------------------------------------
x = 2 
    y1 = 4^-(2) = 4^(-2) = 1/16 
    y2 = 2^(-(2) + 1) = 2^(-2+1) = 2^(-1) = 1/2
y1 ≠ y2      =>      so x=2 isn't our answer

Which means that our final answer is: x=-1


C) You should draw both graphics, and their intersection point (x) will be the answer.


I hope it helped.
