Question

Y=-3x+7

a) what is the domain?
b) what is the range?
c) is the relation a function?

Answer 1

For the domain, you can put any real value as there is no restriction here
For the range also you can get any real value

Is it a function?
Ofc it’s a function, the equation represents a line which clearly doesn’t give 2 values of y for 1 value of x
