Question

p0sitr0n · Answer

(3x+7)^1/2
square root could only be taken for 3x+7>=0
3x>=-7
x>=-7/3

dom; [-7/3,+infinity[
guess its that

thank you @P0sitr0n ! can you answer this one? given f(x) = -2x+5 use the input values -3,0,2,5 to create a complete relation. then display this relation in 4 different ways.

p0sitr0n · Answer

i dont really get what the 4 different ways mean,  but i guess those numbers are to be placed either in the x or the y and need to make the equation true.
f(-3)=11
f(0)=5
f(2)=1
f(5)=-5
i guess the relation is linear as it is a line passing throught (0,5). sorry, i just dont get the 4 different ways part
