Answer:

The roots are -5, 1.

Step-by-step explanation:

$f(x) = x^2 + 4x - 5$

The roots of a function are also the Ox intercepts, so basically we're finding when is the function equal to '0'.

$x^2 + 4x - 5 = 0\\(x-1)(x+5) = 0\\x_1 = 1, x_2 = -5$

Previous crime rate = c incidents per 1,000 people

Reduction in crime rate after batman brought the joker to justice = 12%

Hence, new crime rate (per 1,000 people) would be = c - 12%×c

⇒ New crime rate (per 1,000 people) would be = c - 0.12×c

⇒ New crime rate (per 1,000 people) would be = 0.88×c

Hence, now the crime rate is 0.88×c per 1,000 people.
