Question

Evaluate the piecewise function at the given values of the independent variable.

Answer 1

Answer:

Step-by-step explanation:

Piecewise function 'f' has been given as,

f(x) = 4x + 3 when x < 0

        (x + 7) when x ≥ 0

By using the piecewise function,

a). f(-2) = 4(-2) + 3  (Use f(x) = 4x + 3, since x = -2 is less than 0)

           = -8 + 3

           = -5

b). f(0) = 0 + 7 (Use f(x) = x + 7, since x = 0 is equal to 0)

           = 7

c). f(1) = 1 + 7 (Use f(x) = x + 7, since x = 1 is greater than 1)

         = 8
