Part 2) The Golden Gate Bridge is a suspension Bridge spanning the Golden Gate, a short strait in San Francisco. It is one of the wonders of the Modern World and it was opened in 1937. It cost around 500 million dollars in today's currency and it is one of the longest suspension bridges in the world and from land to land the distance is 1280 m. The height of the suspensions is 230 m.
Part 3) We can think of a parabola of the form y=ax^2 where we need to substitute the values to find a.

Standard quadratic equation .. y = a x^2 + b x + c
parabola 'a' not equal to zero 
a<0 parabola opens downward 
a>0 parabola opens upward 
when |a| >>0 the parabola is narrower 
when |a| is close to zero , the parabola is flatter 

when the constant is varied it only effects the vertical position of the parabola , the shape remains the same
