Question

sketch the graphs of the following functions. write their domain and rang a)f:R-R defined by f(x)=-x^2​

Answer 1

Answer:

A function which always gives a non negative real value irrespective of the input values is called a modulus function.

It is given as

f(x)=∣x∣={

x,x≥0

−x,x<0

Henc the graph of f(x)=∣x∣.

Answer 2

Step-by-step explanation:

Parallel Plate Capacitor Formula

The direction of the electric field is defined as the direction in which the positive test charge would flow. Capacitance is the limitation of the body to store the electric charge. Every capacitor has its capacitance. The typical parallel-plate capacitor consists of two metallic plates of area A, separated by the distance d.

The parallel plate capacitor formula is given by:
