Answer:
50% of what number is 11.72 = 23.44
Step-by-step explanation:
50% is half, so simply doube it.
Y = f (x) = 19 / x^3 and g (y) = x
<span>g is inverse of f </span>
<span>x^3 = 19 / y </span>
<span>x = [ 19 / y ]^(1/3) </span>
<span>g (y) = [ 19 / y ]^(1/3) </span>
<span>g (x) = [ 19 / x ]^(1/3)________inverse function.</span>
R(x) is a polynomial. Thus, the domain is the same as the range.
Domain = range = ALL REAL NUMBERS.
We can also express the answer as
(-infinity, infinity).
