Question

The domain of f(x) is {−1, 0, 2}. If f(x) = 3x + 2, what is the range?

Answer 1

domain= x values
range = y values
substitute x for given x values simplify the function that will give you the y-values(range)

Answer 2

ah oik thx

Answer 3

if you have a question about it you can ask me :=))

Answer 4

i'll do first one for you
first x value is -1
x=-1
\[\large\rm f(x)=3\color{Red}{x}+2\]
f(x) is same as `y`
\[\large\rm y=3\color{Red}{x}+2\]
replace x with -1
\[\large\rm y=3\color{Red}{(-1)}+2\] \[\large\rm y=-3+2=-1\]

Answer 5

(-1,2,8) range of the function
