Answer:
f (
x
) −
1 =
(
1/
4 x
) −
2.
Step-by-step explanation:
For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:
f (
x
) = 4
x + 8
f (
x
) = y
y = 4
x + 8
x = 4
y +
8 ----- interchanging y and x
Now make y the subject of the equation:
x = 4
y + 8
−
4
y = -
x + 8
y = (
−
1/
4 )
. − x
+ (
−
1/
4 ) .8
y = (
1/
4 x
) −
2
So the inverse function is:
f (x) −
1 = (
1/
4 x
) −
2
According to financial advisers,
<span>* mortgage payment should be at most </span><span>28% of your gross monthly income
</span><span>* total monthly debt should be at most </span><span>36% of your gross monthly income. Total monthly debts include </span><span>mortgage payments, car payments, credit card bills,
student loans, and medical debt.\</span>
<span>gross annual income: 39,600</span>
gross monthly income: 39,600 / 12 = 3,300
a) maximum amount for monthly mortgage payment: 3,300 x 28% = 924
b) maximum amount for total credit obligations: 3,300 x 36% = 1,188
c) mortgage: 924 x 70% = 646.80 actual mortgage
1,188 - 646.80 = 541.20 maximum amount they could spend each month for all other debts.
