Answer:
f(x/4)
Step-by-step explanation:
The red and orange lines are when f(x) is stretched vertically.
The blue line is when f(x) is stretched horizontally.
Comparing the blue line to f(x), we see that it is 4 times wider. Therefore, the blue line is f(x/4).
Cone's volume is third of cylinder's volume, so 321*1/3=107 cubic units. Answer A. is correct.
The equation that is given in this item can be mathematically expressed as,
f(x) = (x/7)^(1/3) - 9
The expression f(x) can be replaced with y such that the equation can also be written as,
y = (x/7)^(1/3) - 9
The first thing that needs to be done to get the inverse of the function is to interchange the positions of x and y. In this equation, that becomes,
x = (y/7)^(1/3) - 9
Then, solve for the value of y in terms of x.
Transpose the constant to the other side of the equation.
x + 9 = (y/7)^(1/3)
Raise the whole equation by 3 in order to eliminate the radical.
(x+9)³ = (y/7)
Multiply the equation by 7 to eliminate the fraction.
(x+9)³(7) = y
Thus, the inverse of the function is equal to
<em> f⁻¹(x) = 7(x+9)³
</em><em />The answer is letter B.<em>
