### Python Homework #1

**Create the functions below in a single file and upload that file to
the homework server.**

**Exercise #1:**

Create the function fahr_to_cel(temp)
which will return the temperature in Celsius, given the temperture in
Fahrenheit.

Example usage:

print('Freezing point of water is: ',fahr_to_cel(32),
'and the boiling point is: ',fahr_to_cel(212))

print('The temp in Celsius at -40 degrees Fahrenheit is: ',fahr_to_cel(-40))

**Exercise #2:**

Create the function dist(x,y) which
will be given the coordinates of a point in the plane (x and y) and return the
distance from the origin.

Example usage:

print('This should be 5: ',dist(3,4))

**Exercise #3:**

Create the function eval_quad(a,b,c,x) that
will calculate the Y value given the coefficients a, b, c and the value of x of
the equation Y = aX^{2} + bX + c.

print(eval_quad(1,1,1,2)) should print 7

print(eval_quad(0,2,1,4)) should print 9
