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
