What is the range of the function f(x)=-x^2+4 when the domain is -3,-1,2

  the range is {-5, 0, 3}

Step-by-step explanation:

The range is the set of values the function takes on when x is in the domain. The calculator shows us ...

  f(-3) = -5

  f(-1) = 3

  f(2) = 0

So, the range is the set of values {-5, 0, 3}.

Comment on the set

The values don't have to be presented in any particular order. For many purposes, it is helpful to have them ordered least to greatest. For the purpose of matching range values to domain values, a different order may be preferred.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
