Question

Which logarithmic graph can be used to approximate the value of y in the equation 6y = 12

Answer 1

these are the graphs

Answer 2

@jdoe0001

Answer 3

\(\Large 6^y=12\quad ?\)

Answer 4

yes sorry I forgot to make y an exponent

Answer 5

well... I assume you're meant to graph it, then check against the choices

Answer 6

I don't know how to graph this because every online graph doesn't understand...

Answer 7

hmm well ... have you covered logarithms much?

Answer 8

yes I just cant remember at the time

Answer 9

could you tell me how to do this so I can finish :) this is my last question

Answer 10

I'm thinking you'd need to graph it to match it up

lemme use the "log change of base formula" so \(\bf log_{\color{red}{ a}}{\color{blue}{ b}}=y\implies {\color{red}{ a}}^y={\color{blue}{ b}}
\\ \quad \\ \quad \\
{\color{red}{ 6}}^y={\color{blue}{ 12}}\iff log_{\color{red}{ 6}}{\color{blue}{ 12}}=y
\\ \quad \\
\textit{log change of base rule }
\\ \quad \\
log_{\color{red}{ 6}}{\color{blue}{ 12}}=y\implies \cfrac{log(12)}{log(6)}=y\)

so... graph that, and match against the choices

Answer 11

ok thank you!!! :)
