Answer 1

Evaluating the piecewise function when X =3, we get f(3) = 7

Explanation:

Given the following piecewise function

f(x)= { 2x+1; where x > 0

-3 when x ≤ 0

Evaluate the function when X = 3

We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0

We can't use -3, because x ≤ 0, and 3 is not less than 0.

Now, evaluating the function:

`f(x)=2x+1\\Put\:x=3\\f(3)=2(3)+1\\f(3)=6+1\\f(3)=7`

So, Evaluating the piecewise function when X =3, we get f(3) = 7
