Find the range of the function y=-x^2-3x when the domain is {-5,0,2}

umka21 [38]

Answer: $\{-10, 0 \}$

Step-by-step explanation:

The range is the set of output values for the domain (the set of inputs).

When x=-5, y= $-(-5)^{2}-3(-5)=-10$ .
When x=0, $y=-0^{2}-3(0)=0$ .
When x=2, $y=-2^{2}-3(2)=-10$

So, the range is $\boxed{\{-10, 0 \}}$
