What is the Most basic function in the linear function family?
parent
Which line has no endpoint and goes on forever?
A line representing any polynomial function, power function (including negative powers), trigonometric functions, most continuous probability distribution functions.
Is The negative square root of x minus five a function?
No, it is not. -√(-5) can be written many ways -5i is the most common, but once you get into complex numbers, functions change. -5i5 is also valid, -5i9 is also, and so on. There must be a limit on complex functions, since they do not behave the same as real functions. ■
What are the basic trigonometry functions?
The 3 most common trigonometry functions are as follows:Sine (opposite/ hypotenuse)Cosine (adjacent/hypotenuse)Tangent (opposite/adjacent)An easier way to remember these is SOH-CAH-TOA which, when pronounced out-loud, sounds kind of like "soak a toe".
Real life situation involving function examples?
Functions are an integral part of mathematics, and most students learn them from Algebra II and up. A real life example of a function would be the relation between the height of a ball and how long it has been in the air.
