Answer to any question will be appreciated. If you can please explain to me how you got the answer :)

1. xeR     3. f(0)=1

Step-by-step explanation:

The domain of an expoential fuction is the set of all real numbers.

to find y-intercept substitute x=0

  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.
