The capacitive reactance, the inductive reactance, and the resistance of the circuit can be combined to give the impedance ZZZ of the circuit. The impedance is a measure of the total reactance and resistance of the circuit and is similar to the equivalent resistance that can be found from various resistors in a dc circuit. Because vLvLv_L and vCvCv_C do not reach maximum values at the same time as iii, the impedance is not found by adding RRR, XLXLX_L, and XCXCX_C. Instead, the impedance is found using.

Why can't you figure it out?

Explanation:

the answer for apex is the lowest

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
