Answer: y = +/- [√x+4) ] / 3
Explanation:
1) To find the inverse of the function y = 9x^2 - 4, exhange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 - 4 → x = 9y^2 - 4
3) Solve for y:
9y^2 = x + 4
y^2 = [x + 4] / 9
y = +/- [ √ (x + 4) ] / 3

Answer:
Step-by-step explanation:
Step one:
the original price of refrigerator = $650.20
the markup/raise is 50%
the new price after the raise is
= 50/100*650.20
=0.5* 650.20
=325.1
The raise is by $325.1
The new price is $325.1+ $650.20=$975.3
Step two:
there was a discount of 70%
so =(70/100)*975.3
=0.7*975.3
=682.71
The discounted price is $682.71
The new price is 975.3-682.71
=$292.59
