Question

Evaluate the function when x=5
F(5)=?

Answer 1

Explanation:

When evaluating piecewise function, make sure the x value satisfies the function we use.

since 5>3, we use the second equations

That function is a constant function, this means at any x>3, exclusive, we will have a y value of -1.

So

`f(5) = - 1`
