If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
Def. Scalar function. A scalar function is a function that assigns a real number (i.e. a scalar) to a set of real variables. Its general form isu = u(x1, x2, ... , xn)where x1, x2, ... , xn are real numbers.ORDef. Scalar point function. A scalar point function is a function that assigns a real number (i.e. a scalar) to each point of some region of space. If to each point (x, y, z) of a region R in space there is assigned a real number u = Φ(x, y, z), then Φ is called a scalar point function. Examples. 1. The temperature distribution within some body at a particular point in time. 2. The density distribution within some fluid at a particular point in time

consider a two port network. if u take the ratio of output of one port either current or voltage/ input of other port either voltage or current, if it is same parameter ie. V2/V1 then we call it as transfer function or gain also. V1 is the input port voltage and V2 is the output port voltage. In s domain also we can call it as transfer function, and also not necessary restricted to s-domain only. Suppose if is of different parameter ie. I1/V2 we can call it as reverse transfer admittance function but thing is to note the presence of 'transfer' term. At the same time the ratio of parameter current or voltage of the same port we call it as driving point function. It can be Admittance function ie. I1/V1 or Impedance function ie. V1/I1

Point function and path function are found in Thermodynamics.
The distance from point A to point B when you are driving on roads.
Since the objective is to find out the impedance between two points, it is advisable to have a meter that has a high input impedance; the higher the better. This is because when the probes are applied across the "impedance" to be measured, the input impedance of the meter is effectively in parallel with the measured impedance. So, if the input impedance of the meter is infinite, the accuracy of measurement will be 100%. Now, let us take a look at the situation on the human body: If the 2 points for measurement are selected on the same acupuncture meridian, the impedance will be lower than if you select one point on the meridian and one point randomly on the other parts of the body. If you select 2 points (not on any meridian) randomly on the human body, the impedance will even be higher. If you are using electrodes with sticky pads for skin contact, the result will be different from that measured with acupuncture needles puncturing the 2 points. Hope this is helpful. K. Kit Sum.

The depth of a lake at a center point is a function of the distance of that point from shore.
At resonance, the L and C impedance cancels out, so the current can be calculated based on the resistance and applied voltage. Imagine increasing frequency of the supply from 0 Hz to very high. At low frequency, the impedance of the inductor is ~0 (defined as Zl = w*L*j), and the impedance of the capacitor is very large (defined as Zc = 1 / (w*C*j)). As you increase the frequency, the impedance of the capacitor will decrease, as the impedance of the inductor increases. At some point (the resonant frequency), these two will be equal, with opposite signs. After crossing the resonant frequency, the inductor impedance will continue growing larger than the capacitor impedance until the total impedance approaches infinite.
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
It means your ultimate conversational point, as if you were driving there.
Yes, in the USA you can basically get from any Point A to any Point B, by driving.
