Hope this helps!
The pictures were not in order on which equation is first so it’s all over the plane
Given:
The function is
![f(x)=x](https://tex.z-dn.net/?f=f%28x%29%3Dx)
To find:
The tangent line to the graph of f(x)=x at point (0,0).
Solution:
We have,
![f(x)=x](https://tex.z-dn.net/?f=f%28x%29%3Dx)
It is a linear function because the highest power of the variable is 1.
We know that the tangent line to a linear function at any point is the line itself.
Derivative of given function is
![f'(x)=1](https://tex.z-dn.net/?f=f%27%28x%29%3D1)
So, slope of the tangent line is 1. It is given table the tangent line passes through the point (0,0). The equation of tangent line is
![y-0=1(x-0)](https://tex.z-dn.net/?f=y-0%3D1%28x-0%29)
![y=x](https://tex.z-dn.net/?f=y%3Dx)
Therefore, the tangent line to the graph of f(x)=x at point (0,0) is y=x.
