Digital photography has dramatically changed the nature of photography. No longer is an image etched in the emulsion on a roll of film. Instead, nearly every aspect of recording and manipulating images is now governed by mathematics. An image becomes a series of numbers, representing the characteristics of light striking an image sensor. When we open an image file, software on a camera or computer interprets the numbers and converts them to a visual image. Photo editing software uses complex polynomials to transform images, allowing us to manipulate the image in order to crop details, change the color palette, and add special effects. Inverse functions make it possible to convert from one file format to another. In this chapter, we will learn about these concepts and discover how mathematics can be used in such applications.

No because a negative times a negative is a positive. No matter what you do you can never multiply the same number by itself and end with a negative

Actually you can. you get what's called an Imaginary number denoted by i which is represented on the complex plane. The reply above would be correct if we were still confined to the "real" number line.

Suppose P= {-3,1,3} Q={-3,-2-1} and R= {-2,2,3}.what is the intersection

Someone should please solve it for me
Add 2over ×+3 +y-4 over 5
simplify (×+a)with square root of two -×root 2 all over a
multiply 1over ×-y{(×-y)(×+y)} over ×y

For the first question, I got (3y-2)/15
Second one, I got Root 2
Third one, I got 1/(y to the fourth power)
I dont if it's right cause I can barely understand the question.

Is under distribute property, inverse function, algebra and addition and multiplication function; so is a combined question

graph the following linear equation using intercepts method.
2x+y=4

Ashley

how

Wargod

what?

John

ok, one moment

UriEl

how do I post your graph for you?

UriEl

it won't let me send an image?

UriEl

also for the first one... y=mx+b so.... y=3x-2

UriEl

y=mx+b
you were already given the 'm' and 'b'.
so..
y=3x-2

Tommy

Please were did you get y=mx+b from

Abena

y=mx+b is the formula of a straight line.
where m = the slope & b = where the line crosses the y-axis. In this case, being that the "m" and "b", are given, all you have to do is plug them into the formula to complete the equation.
