Example of a function with a domain (-∞, +∞) and a range (-∞, +∞)

Hello!

There are endless possibilities to name an example of a function with the domain and range as the set of all real numbers. A type of function that always has the domain and range as the set of all real numbers is linear functions. Some examples of linear function with the domain (-∞, +∞), and a range (-∞, +∞), are as follows:

y = x

y = 5/3x - 9

y = 4x + 3

However, the possibilities are endless. Those three examples are just some of them!

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
