Question

Find v(w + 3) for v(w) = 2w - 1.

Answer 1

v(w+3) = 2w+5 Can someone tell me if this is right ?

Answer 2

\[\large\rm v(\color{orangered}{w}) = 2(\color{orangered}{w}) - 1\]So they want us to evaluate this function at the location w+3.
So instead of plugging 2 into the function, we'll plug w+3 in.\[\large\rm v(\color{orangered}{w+3}) = 2(\color{orangered}{w+3}) - 1\]So you distributed the 2, and 6-1 gave you the 5?
Yay good job \c:/

Answer 3

Instead of plugging w* into the function
blah typo

Answer 4

So am i right ?
