To find the range for the domain : {-2, 0, 3,5} of the function f(x)=-2$x^{2}$ We just plug in the x values in the domain into the function to find the range. When x=-2; f(-2)= -2($-2)^{2}$ = -2(4) = -8 When x=0; f(0)= -2($0)^{2}$ = -2(0) = 0 When x=3; f(3)=-2($3)^{2}$ = -2(9) = -18 When x=5; f(5)=-2($5)^{2}$ = -2(25) = -50
