Answer
The range is {-8, 0, -18, -50} for the domain.
Work Step by Step
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
