Given the function:
y = x^2- 8x+12
(a) Does this parabola open upward or downward?
(b) Find the vertex
(c) Find the axis of symmetry
(d) Find the x-intercepts
(e) Find the y-intercept
(f) Sketch the graph
(g) Find the minimum or maximum value of the function
(h) Find the range of the function

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
