f(x)=5x-2/x^2+3

OpenStudy (solomonzelman):

what do you want to know about this function?

OpenStudy (anonymous):

i need to know what f(2) would be. please

OpenStudy (solomonzelman):

I got disconnected

OpenStudy (solomonzelman):

\(\large\color{black}{ f(x)= \frac{\LARGE 5x-2 }{\LARGE x^2+3} }\) if you wanted to find f(3), \(\large\color{black}{ f(3)= \frac{\LARGE 5(3)-2 }{\LARGE (3)^2+3} }\) \(\large\color{black}{ f(3)= \frac{\LARGE 15-2 }{\LARGE 9+3} }\) \(\large\color{black}{ f(3)= \frac{\LARGE 13 }{\LARGE 12} }\)

OpenStudy (anonymous):

thank you, but what i need is to find f(2):/

OpenStudy (solomonzelman):

so plug in 2 for x to find f(2), just like I plugged in 3 for x to find f(3).

OpenStudy (anonymous):

but i guess i could just plus in 2 for that

OpenStudy (anonymous):

thank you!

OpenStudy (solomonzelman):

yes, have to just replace x with a 2, everywhere, instead of f(x), you will have f(2), and instead of all Xs you have 2s
