# Write a Python function, evalQuadratic(a, b, c, x), that returns the value of
# the quadratic ax^2 + bx + c.

# This function takes in four numbers and returns a single number.

def evalQuadratic(a, b, c, x):
	# a, b, c: numerical values for the coefficients of a quadratic equation
  # x: numerical value at which to evaluate the quadratic.

  return a * x**2 + b * x + c
