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.

That looks right.

Not for the function you have above, no.

y doesnot equal 4** sorry typo
anonymous
  • anonymous
y can equal 4 here, just not anything above it.
anonymous
  • anonymous
my solution says it says y can equal any real number :S
anonymous
  • anonymous
yeah i thought it was that too,

Not for a parabola it can't.

The domain is any real number for x...

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

maybe she made a mistake :S

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

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