There is no solution for it
Y int: 5
equation: -2/3x +5
slope: -2/3
Given equation is
.
Now we need to find about what are the key aspects of the graph of
, where b is a real number.
We know that square of any number is always positive.
then
must be a positive number.
So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by
units as compared to the graph of parent function 
- 5z^3 - z^4 + 4z^5 is the answer.
