## anonymous 3 years ago Describe the transformation for : y= -x²+6x-5

1. anonymous

The parent function is the squaring function, $$y=x^2$$ Look at all the ways $$y= -x^2+6x-5$$ is different from the parent function. Putting it in vertex form will also help.

2. anonymous

how do i do that ? :\$

3. anonymous

Vertex form? Complete the square.

4. anonymous

ohhh okay !

5. anonymous

$\huge -(x-3)^2+4$

6. anonymous

That looks right.

7. anonymous

$\huge Range = {\epsilon \mathbb{R}| y \neq 0}$

8. anonymous

Not for the function you have above, no.

9. anonymous

y doesnot equal 4** sorry typo

10. anonymous

y can equal 4 here, just not anything above it.

11. anonymous

my solution says it says y can equal any real number :S

12. anonymous

yeah i thought it was that too,

13. anonymous

Not for a parabola it can't.

14. anonymous

The domain is any real number for x...

15. anonymous

yeah that's what i thought, look at number 8 http://mail.wecdsb.on.ca/~janet_maitland/FOV1-0006CFBC/FOV1-0006E9C7/unit%20three%20practice%20answers.pdf?Plugin=Loft

16. anonymous

maybe she made a mistake :S

17. anonymous

Yeah, you can see clearly from the graph that the range is y≤4.

18. anonymous

okay thanks :D i thought i might have been doing to wrong
