Question

Evaluate the given functionf(x)=4; find f(-2) and f(0.3)

Answer 1

We have the next function

$f(x)=4$

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

$\begin{gathered} f(x)=a \\ \text{ In this case,} \\ a=4 \end{gathered}$

That means, for any value of x the function will always be equal to 4.

Using that, we obtain

$\begin{gathered} f(-2)=4 \\ \text{ and,} \\ f(0.3)=4 \end{gathered}$

ANSWER:

f(-2) = 4

f(0.3) = 4
