When viewing big ben in london, you decide that you want to visit the jubilee gardens. instead of traveling by car, you take a boat ride to the jubilee gardens. using the map below, calculate the distance you traveled from big ben to the jubilee gardens by boat. show all work and explain each step of your calculations.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
