Check the picture below.
notice the solid circle at -4 and 3, since it includes those points.
also notice the dashed line, though the lines keeps on going those ways, is not included in the piece-wise, since it's not part fo the domain or constraints.
Sale price = original price - discount
discount = 44% of original price = 44% of $37 = 0.44 x 37 = $16.28
Sale price = $37 - $16.28 = $20.72
12 mixed nuts packs
Explanation:
The box weighs 16 1/2 ounces
1 mixed nut = 1 3/8 ounces
let the number of fruit mixed nut in the box = y
1 mixed nut = 11/8 ounces
y = 33/2 ounces
cross multiply:


14 = M each on would be *t=5
Let f(x) be y.
y = x³ + 3
Switch x and y:
x = y³ + 3
Now you need to isolate y and you would get inverse function.
x - 3 = y³
∛(x-3) = y
Final answer: f ⁻¹(x) = ∛(x-3)
Hope this helps.
