tolong di jawab ya^^

no.5
diket: f(v)=8v-3
(f o g)(v)=24x + 29
ditanya: rumus fungsi g(v)?
di jawab:
[tex] (f \: o \: g)(v) = 24v \: + 29 \\ f(g(v)) = 24v \: + 29 \\ 8(g(v)) - 3 = 24v \: + 29 \\ 8(g(v)) = 24v + 29 + 3 \\ 8(g(v)) = 24 v + 32 \\ \frac{8(g(v))}{8} = \frac{24v + 32}{8} \\ g(v) = 3v + 4[/tex]
jadi rumus fungsi g(v)=3v +4.
semoga membantu dan tolong di crosschek lagi..
