First order the prices

3,16,17,18,18,21,23,24,125

range
125-3= 122

18 median
Q1= 16+17 /2= 33/2= 16.5
Q3= 23+24 /2= 47/2=23.5

IQT= 23.5-16.5=7

How to solve X^4-19x^2+48=0
ZanzabumX [31]
Two numbers that add up to -19 and multiply to 48 are -16 and -3:

(x^4-19x^2+48)=0\\(x^2-16)(x^2-3)=0\\(x+4)(x-4)(x^2-3)=0

So, the solutions come from each parentheses:  x+4=0, x-4=0, and x^2-3=0.

x+4=0
x = -4

x-4=0
x = 4

x^2-3=0
x^2 = 3
x = +/- √3

So, the solutions are -4, -√3, √3, and 4.

Here, Alicia is wrong because on evaluating 3 ^{1.4} we get 4.65554 which is of course less than 6. Zara's calculation could be;

3 ^{1.4}  \\  \\ 3 ^{ \frac{7}{5} }  \\  \\  \sqrt[5]{3 ^{7} }   \\  \\ 3 \sqrt[5]{3 ^{2} }  \\  \\ 3 \sqrt[5]{9}  \\  \\  = 4.6554

(Algebra 2)<br><br> Find the inverse of f(x) and its domain.
elixir [45]
Let f(x)=y
f^-1(x)=x
y=1/(x+5) - 1
y+1=1/(x+5)
(x+5)=1/(y+1)
x=1/(y+1)-5
f^-1(x)=1/(x+1) -5

denominator cannot equals to zero
x+1≠0
x≠-1
