Determine the range of the function in the table below

Question

×=-25,-22,-20,-15

 

F(×)=31,17,9,27

 

Answer 1

Domain is the values that x can be

x∈{-25,-22,-20,-15}

 

Range is the values that y can be.

f(x) = y is function notation for finding y (read "f of x") to show that y is dependent on x

y∈{9,17,27,31}
