Given the formula found in part I, An=505⋅0.9n, estimate the number of businesses in 2020.

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5

y-y1=m(x-x1)

y-1=1(x-8)
