+1347 The function $f(x)$ is defined only on domain $[-1,2]$, and is defined on this domain by the formula
$$f(x) = 2x^2-8x+1.$$
What is the range of $f(x)$? Express your answer as an interval or as a union of intervals.
+2 range of \({f(x) = 2x^2 - 8x + 1}\) 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:
[\({-7}\),\({11}\)]
+2440 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...
