Question

Graph f(x)=4⟦x⟧ +5

Answer 1

is that the absolute values delimiters around the x?

Answer 2

I honestly have no clue. Every time I went to enter it into Desmos or WolframAlpha, they did not recognize the symbol. It's on my homework paper, though. If it helps my assignment is on Piecewise functions..

Answer 3

@UnkleRhaukus

Answer 4

have you been learning about absolute values ?

Answer 5

yes

Answer 6

well then, i will assume your question is this

\[ f(x)=4|x| +5\]

Answer 7

can you plot

\[f(x) = 4x+5\]
( for x's that are positive only)

Answer 8

and \(f(x)=-4x +5\) ror negative x's

Answer 9

\[f(x)=4|x| +5\iff\begin{cases}f(x)=\,\,\,\,\,4x +5&x\geq0\\f(x)=-4x +5&x\leq0
\end{cases}\]
