A scale drawing of a car uses a scale of 1 inch = 3 feet. The length of the car in the scale drawing is 6 inches. Which proportion can be used to find the length of the actual car? A. 1/3 = x/6
B. 3/6=1/x
C.1/6=x/3
D.1/3=6/x

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

x = 1/2

step-by-step explanation:
