## Homework Statement

Question: Determine the equations of both lines that are tangent to the graph of f(x) = x

^{2}and pass through point (1,-3).

## Homework Equations

Some of the equations that I could use for this problem are:

y-y1=m(x-x1) (Point-slope Equation)

the derivative of the function f(x) from first principles (the limit of the difference quotient, as h approaches 0)

## The Attempt at a Solution

First, I took the derivative of the function x

^{2}.

As a result,

f`(x) = 2x

But I'm not sure on how to go from here.
