A hotel entrance makes a parabolic arch that can be represented by a quadratic function, f (x) = - x^2 - 4x + 12, where y is the height of the arch and x is the distance from wall to wall in feet. What is the distance between the two walls of
the arch?

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
