-3.
It's the same as normal division unless they have different signs, then it's negative.
All the linear functions in form y = mx + b where m ≠ 0 has the inverse in form
y = x/m - b/m.
Answer: The inverse of f exist.
Ok so from experience on this site
3x2=3x^2
people don't know how to put exponents
3x^2-y^3-y^3-z
simplify first
3x^2-2y^3-z
x=3
y=-2
z=-5
3(3^2)-2(-2)^3-(-5)
3(9)-2(-8)+5
27+16+5
48
19.5 because 6 minus 5.5 is equal to 0.5 and if you just add 0.5 to 19.5 it will be 19.5
