1' = 12"

The scale; 1/4" : 1' → 1/4" : 12" → 1" : 48"

Actual large is 48 times greater than on the architectural drawing. Therefore:

2 1/2" = 2.5"; 3 3/4" = 3.75"

2.5" → 2.5" · 48 = 120" = (120 : 12)' =10'

3.75" → 3.75" · 48 = 180" = (180 : 12)' = 15'

A. 10ft by 15 ft.

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.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
