What is the transformations of f(x)=(x-2)^2-4
prisoha [69]
This is how to solve the problem: "What is the transformations of f(x)=(x-2)^2-4"

Looking at the quadratic equation given,
f(x)  = (x-2)^2 - 4
It's like seeing product of sum and difference of two squares.

(x-2)^2 - 4
[ (x-2) - 2 ] [ (x-2) + 2 ]
[ x - 2 - 2 ] [ x - 2 + 2 ]
[ x - 4 ] [ x ]
[ x^2 - 4x ]

So the final transformation of f(x) = (x-2)^2 -4 is f(x) = (x^2 - 4x). 
In this way, we are able to show how a complicated equation to simple yet equal equation in quadratic form.

Find the surface area of the composite figure.
wolverine [178]

The Surface area of the figure is 520 square centimeters

<h3 /><h3>How to calculate the surface area of a figure</h3>

The figure is made up of rectangular prisms

The formula for calculating the surface area of rectangular prism is expressed as:
SA = 2(lw + wh + lh)

l is the length

w is the width

h is the height

Surface area of the figure = 2(2(8) + 2(14) + 8(14)) +  2(6(8) + 6(4) + 8(4))

Surface area of the figure = 2(16+28+112) + 2(48 + 24+32)

Surface area of the figure = 312 + 208

Surface area of the figure = 520 square centimeters

Hence the Surface area of the figure is 520 square centimeters
