Question

given f(2)=1 and the fact that g(x)=-2f(x-1)+5 to find g(3)

Answer 1

when x=3, we know f(3-1) ....

Answer 2

Sorry I don't understand?

Answer 3

the information provided is rather simple to follow ...

f(2) = 1

what is f(3-1) ?

Answer 4

Where did you get f(3-1) ?

Answer 5

Sorry I don't understand?

Answer 6

g(x) relates to g(3) by letting x=3

Answer 7

since they give you: \[g(x)=2~\color{red}{f(x-1)}+5\]
and say to find g(\(\color{orange}3\))

Answer 8

\[g(x)=-2~\color{red}{f(x-1)}+5\]
\[g(3)=-2~\color{red}{f(3-1)}+5\]
\[g(3)=-2~\color{red}{f(2)}+5\]

Answer 9

they say f(2) = 1 sooo ....
\[g(3)=-2~\color{red}{f(2)}+5\]
\[g(3)=-2~\color{red}{*1}+5\]
\[g(3)=-2+5\]

Ok thank you!

Answer 11

yep
