Question

whats the domain and range of f(x) = 3x^2+4x-5

Answer 1

I think it's:

Domain=All real numbers
Range=All reals greater than or equal to -6.33333333

Answer 2

can you show the work for that and thank you

Answer 3

What I did is graph it on my calculator. It is a parabola, and since it keeps going out there are infinite x values (hence the domain of all real numbers). The lowest point that the parabola reaches is -6.3 repeating, so there are no y values after that. That would make the range -6.33333

Answer 4

ok thank you so much

Answer 5

you're welcome
