Question

2x-5 if x is less than or equal to 0
f(x)= -x+1 if x > 0

How do i find the domain and range and points to graph it

Answer 1

after the F(x) there is this symbol

Answer 2

can anyone figure this question out

Answer 3

i am lost

Answer 4

Domain- All the possible x values you can plug into the equation and still obtain a real result.

Range- All the possible y values that could result by plugging in every possible x

Answer 5

to remember which is which:
"domain, range"
" x , y "

they come in the same order

Answer 6

is there any x's you are not allowed to plug into that?

Answer 7

no i dont know

Answer 8

Plot each equation as you would normally, for the first, you want to plug in numbers that are 0 and below, for the second, any numbers 1 and above. You should be able to find the domain and range based on this.

Answer 9

For X =< 0, use the first function to plot, for X > 0, use the second function to plot.
