The function $f(x)$ is defined only on domain $[-1,2]$, and is defined on this domain by the formula
f(x)=2x2−8x+1.
What is the range of $f(x)$? Express your answer as an interval or as a union of intervals.
range of f(x)=2x2−8x+1 if restricted to -1 ≤ x ≤ 2, or domain [-1,2]
f(−1)=2∗(−1)2−8∗(−1)+1=11
f(2)=2∗(2)2−8∗(2)+1=−7
so, range is:
{f(x) element R:−7≤f(x)≤11}
interval:
[−7,11]
For the record: "TheGingeriousAle" account is not under the control GingerAle.
.... I was wondering when you’d return... and what user name you’d create to impersonate GingerAle. TheGingeriousAle is a likeable name. I’m rather amazed an obnoxious and noxious troll could create the name. ...Perhaps you didn’t. If you used an AI then it’s not really your creation.
You posted a correct math solution (without bullshit), which is also amazing...and you didn’t sign my initials. Is this a change in tactics or will the familiar “other shoe” drop in a future post?
...In any case, impersonating another member is a violation of the TOS. So this account, like all the others impersonating GingerAle, is subject to banning. ...And banned it will be, eventually...
