Answer:
a) (x/7)^1/9=y
Step-by-step explanation:
f(x) = 7x^9
x/7= 7y^9/7
(x/7)^1/9=(y^9)^1/9
(x/7)^1/9=y
f^-1(x) is a fuction because it passes the vl test

Find the percentage of the household that didn't receive basic cable
100% - 88% = 12%
<em>This is the percentage of the household that didn't receive basic cable by the household owned TV set.</em>
Now find the number with the percentage
without basic cable = 12% × 114.9 million
without basic cable = 12/100 × 114,900,000
without basic cable = 13,788,000
<em>The number of households that didn't receive basic cable is 13,788,000 or 13,788 million</em>
