Question

how do i solve f(x)=2t=t squared

Answer 1

t=0

Answer 2

or
\[2=t\]

Answer 3

i assuming you intended to but two equal signs

Answer 4

yes i got that answer but my book say - infinity to infinity why is that instead of 0 to infinity

Answer 5

negative infinity does not work

Answer 6

why does it not work?/

Answer 7

problem says find the domain of f(t)=2t+t squared i'm confused

Answer 8

well
\[f(x)=2t=t^2 \]
\[f(-∞)=2\times-∞=-∞\]
however\[(-∞)^2=∞\] (negative times negative is positive

Answer 9

I see now... so that makes the domain -infinity to infinity
