because your function is y=3x+7 and this is defined for whole real numbers

@hiralpatel121 clear??

Okay. So the the answer is the same for both the domain and the range?
hartnn
  • hartnn
domain means all the values that t can take so that the function does not become complex,or become undefined if we observe in V(t) = -203t+9655 for any value of t ,V(t) will be defined. so domain=(-infinity,infinity)
ghazi
  • ghazi
yes
hartnn
  • hartnn
range mean all the values V(t) can take as its a linear function,it can take infinite values depending on infinite values of t hence range is same.

still doubts regarding this?

No, I've got it. I need help with doing parts of number 1 though. I tried to do it but then I got confused.

find all x where f(x)=304 this??
ghazi
  • ghazi
3x+7=304 3x=304-7 3x=297 x=99
anonymous
  • anonymous
That would be the answer for where f(x)=304?
ghazi
  • ghazi
yes

What about parts (d) and (e) for number 1? How would I do those?
hartnn
  • hartnn
for part e, same logic as #2 same domain,range.
ghazi
  • ghazi
you have set of points like let's say two variables are x and y now you have (-6,-11) , (-2,1) and (0,7) plot this on graph paper
ghazi
  • ghazi
your graph will tell you the domain and range
