Domain is the number of x values that can be used and not cause an imaginary result.
Range is the number of the y values that result.
In f(x)=2x-5 the range is all real numbers.
True
please elaborate your question
The range depends on the domain and conversely.
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide
Domain : set of all reals Range: set of all reals

2x = 5 x = 2.5
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
If your question was 2X + 5 =10. X equals what? Then X=2.5
-3
2x=5 x=5/2 x=2.5
