Actually Welcome to the Concept of the Modulus functions.
Since here, the value of h and k are zero,hence
the value of the function f(x) = 3|x| is 3
====> answer is 3
No one cares but the answer probably is 5 70
1/2 x^2 - x + 5 = 0
Multiply through by 2 to get:
x^2 - 2x + 10 = 0

; where a = 1, b = -2 and c = 10

Therefore, x = 1 + 3i or x = 1 - 3i
