what is this

OpenStudy (solomonzelman):

\(\large\color{#000000 }{ \displaystyle f(x)=2-3x }\) You need to find f(-4), but if I were to solve for f(-6), then this is what I would do: \(\large\color{#000000 }{ \displaystyle f(\color{#0000ff}{-6})=2-3(\color{#0000ff}{-6}) }\) \(\large\color{#000000 }{ \displaystyle f(\color{#0000ff}{-6})=2+18=20 }\)
