Question

find domain and range of y=-2x+14

Answer 1

domain should be the values belonging to x for which a function is defined

Answer 2

you should write it this way

\[f(x)=-2x+14\]

Answer 3

now what values go into x that make this function valid

Answer 4

i can say domain is \[x \epsilon \mathbb{R} \]

Answer 5

x belongs to the set of real numbers

Answer 6

to find the range you need \[f ^{-1} (x)\]

Answer 7

to find inverse turn f(x) to y and make x the subject

Answer 8

\[f ^{-1} (x) =\frac{ x-14 }{ -2}\]

Answer 9

the range too is the set of Real numbers
