In order for a reaction to begin, what is required?

activation energy
ionic bonding
precipitate forming
bubbling

Answer;

Activation energy

Explanation;

Activation energy is the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.

Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.  The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

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 .
