Answer:
(a) h^-1(x) = (x+6)/6
Step-by-step explanation:
The inverse relation can be found by solving for y: x = h(y).
<h3>Solution</h3>x = h(y) . . . . . the inverse relation
x = 6y -6 . . . . . use the function definition
x +6 = 6y . . . . add 6
(x +6)/6 = y . . . . divide by 6
The inverse function is ...

Any number is equal to that number over 1
So x is equal to x/1
Same thing with 24. 24 = 24/1
To get it into percent we multiply by 100 so:
And simplifying that we get
And x/100 = x%
so 2400/100 = 2400%
So your answer is <em><u>2400%</u></em> :)
