Consider the function f(c) = 1 Di-l(ki – c)2. In this scenario, suppose that our data points X1, X2, ..., In are fixed, and that c is the only variable. Using calculus, determine the value of c that minimizes f(c). You must justify that this is indeed a minimum, and not a maximum.

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
