Answer:
the transformed function will be:
Step-by-step explanation:
We need to transform into g(x) using following translations
1) reflection in the x-axis
The reflection across x-axis will be:
2) Horizontal shrink by a factor of 1/3
The horizontal shrink by a factor of 1/3 will make the function g(x)
3) Vertical translation up 2 units
The vertical translation up 2 units will make the function g(x)
So, the transformed function will be:
Answer:
7, 4, 3
Step-by-step explanation:
Using Descartes' rule of signs, you can determine there are zero negative real roots. The above answer choice is the only one with no negative zeros listed.
_____
The count of negative real roots is based on the number of sign changes when the signs of odd-degree terms are reversed. Doing that gives the signs of the terms as - - - -, so there are no changes. That means there are no negative real roots.
A graphing calculator confirms this choice.
