A function is that which gives the relation between an input and an output. It is denoted as f(x). Each input value has exactly one output.

Function Calculator calculates the coordinate values for given function and plots the graph for it. If the given function is quadratic, then it calculates the focus, vertex, semi-axis length, focal parameter, eccentricity and directrix. If it is linear function it calculates x-intercept, y-intercept and slope.

## Function Calculator with Steps

Below are given the steps to solve the function:
1. Read the problem and note the given function.
2. Find the values of y by plugging in different values of x. List out all the coordinates and plot the graph.
