How can a quadratic function be a one to one function?

When given a function, draw horizontal lines along with the coordinate system. Check if the horizontal lines can pass through two points. If the horizontal lines pass through only one point throughout the graph, the function is a one to one function.

Why is quadratic a function?

Given a quadratic equation, say y=ax2+bx+c, the independent variable is x, whereas the dependent variable is y. Quadratics have at most two solutions for every output (dependent variable), but each input (independent variable) only gives one value. The function f(x)=ax2+bx+c is a quadratic function.

Can a function be onto and not one-to-one?

Let f(x)=y , such that y∈N . Here, y is a natural number for every ‘y’, there is a value of x which is a natural number. Hence, f is onto. So, the function f:N→N , given by f(1)=f(2)=1 is not one-one but onto.

What is the output of a function?

A functionis a specific type of relation in which each input value has one and only one output value. An input is the independentvalue, and the output value is the dependent value, as it depends on the value of the input.

What is a a function in math?

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input.

What does the function f(x) do with the input?

So f(x)shows us the function is called “f”, and “x” goes in And we usually see what a function does with the input: f(x) = x2shows us that function “f” takes “x” and squares it. Example: with f(x) = x2:

What is a well-defined function?

Strictly speaking, a ” well-defined ” function associates one, and only one, output to any particular input. A function would not be well-defined if say y = f ( x) such that y can take on any number of values at any particular input. Suppose the input x = a outputs more than one distinct value, so that y = f ( a) ∈ { y 1, y 2,…, y k,… } .
