Given function F(x)=3-2x? & Given function g(x)=(x-2) squared?

Question

Given function F(x)=3-2x
what is the domain of f(x)?


Given function g(x)=(x-2) squared
what is the range of g(x)?

thanks much

Answer 1

domain is all the number of x you can have, so in this case all real

range is all the numbers g(x) can have and that is R>= 0

Answer 2

ok .. answer : f ( 0 ) = 0*x - 4 = -4 g ( -4 ) = unfavorable sq. roots are denoted with a imaginary value ' i '. so, its 2i h ( 2i ) = ( 2 * i ) ^ 2 + 9 = -4 + 9 = 5. be conscious: i^2 = -a million or i = sq. root of (-a million) So the in simple terms top answer would desire to be 5.
