We have the next function
And we must find f(-2) and f(0.3)
To find f(-2) and f(0.3) we need to know that
We can see that we have a constant function because it has the next form
That means, for any value of x the function will always be equal to 4.
Using that, we obtain
ANSWER:
f(-2) = 4
f(0.3) = 4
