Question

How do I determine the domain and range of this function F(x) = -3x+8

Answer 1

Domian = All real numbers Since there is no restriction

Answer 2

Domain=R
Range=R
Because no interval in this question

Answer 3

as the function is linear
its domain is all real numbers

Answer 4

For Range take

y = f(x)

y = -3x +8

8 - y = 3x

x = (8-y)/3

So.....Range = All REAL NUMBERS

Answer 5

range is also real numbers

Answer 6

okay so what about for r(x)= SQ ROOT OVER 5-x

Answer 7

\[f(x)= \sqrt{5-x}\]
