Answer:

-1

Step-by-step explanation:

First, we need to find which expression to use for f(1). The first function does not include 1, because it is <, and not [tex]\leq[/tex]

The second functions includes 1, because it has a [tex]\leq[/tex], meaning greater than or equal to, so this is the function we must use.

-x^2

Plug 1 in for x

-(1^2)

Solve the exponent first

-(1)

-1

So, f(1)=-1
