It's been too long, sorry but this a first post.

9th grade son needs to learn how to solve this function and I'm rusty. Don't need it solved just a push in the right direction please.

f(x)=(-3-10x)/(10x^2 -7-15x), find f(-6)

I'm thinking that I plug the -6 in for x then solve. Am I correct?

Thanks

an old man....
