Descartes' rule of signs tells you the one sign change in the coefficients means there's one positive real root. If you change the sign of the odd-power terms, the signs become -++-, so have two sign changes. This means there are 0 or 2 negative real roots.
A graph shows there to be 3 real roots, two of which are negative. Thus there are no complex roots.

Answer:
See below
Step-by-step explanation:
<u>Parent function:</u>
- y = √x
<u>Translation rule:</u>
- (x, y) → (x - 3, y + 1)
It will translate right 3 units and up 1 unit
<u>The translated function is:</u>
- f(x) =
+ 1
Graph is attached where dotted blue is parent function and solid red is translated function
