Question

The equation of the piecewise defined function f(x) is below. What is the value of f(1)?

Answer 1

f(1) = -1

= -(x^2)
= -(1)
= -1

Answer 2

The value of the f(1) should be -1 when the  equation of the piecewise defined function f(x).

Calculation of the value of f(1):

here first we are required to determine which expression to use for f(1). The first function does not involve 1, because it is <, and not ≤

And,

The second functions involved 1, because it has a ≤ that  meaning greater than or equal to, so this is the function we must use.

So, it can be like

f(1) = -1

= -(x^2)

= -(1)

= -1

hence,

The value of the f(1) should be -1 when the  equation of the piecewise defined function f(x).
