I'm having some problems, obviously, with some of my math work. There's a few different ones so hopefully this will all make sense...
Any help would be appreciated.
1. Evaluate the function for the given values:
I'm not sure where to go with that one. I'd assume I'd combine like terms (5+4=9, x+3x=4x), though I'm not sure what to do after that. Nor am I sure what to do with the ", 2".
Again, I'm not really sure where to go with this. I've always struggled greatly with fractions...
3. Solve and list the answer in Set Builder Notation:
For this one I've got the equation down to...
But I'm not sure what to do from there... (I think I did my combining correctly...?)
And one last question... I've got a problem similar to number 3, however instead of it saying to list the answer in Set Builder Notation it just says to list it graphically. How would I list it graphically? I'm not entirely sure what it's asking me to do.
The problem is almost identical to number 3, just different numbers.
Thank you for your time and for your help!
