functions whose highest exponent of the variable is 2. Parabolas have a single vertex and ‘x’ and ‘y’

intercepts. Parabola calculator is the online tool which can instantly calculate the details regarding the shape

of a parabola.

Given quadratic equation: f(x)= x

Since the given function is in the form of f(x)= ax

Hence we can find the ‘x’ coordinate of the vertex by using->

In our given equation, a= 1; b= -6; c= 8

x= -(-6)/ (2 * 1)

x= 6/2->

Hence f(3)= 3

Given quadratic equation: f(x)= x

Since the given function is in the form of f(x)= ax

Hence we can find the ‘x’ coordinate of the vertex by using->

In our given equation, a= 1; b= -2; c= -15

x= -(-2)/ (2 * 1)

x= 2/2->

Hence f(1)= 1
