Does anyone understand 4.05 f(x)=3(4)

what are you trying to find ?

so if  f(x) equals 3(4) that means f times x so f time x = 3(4) which equals 3 times 4 so f =3 and x=4 so 3 times for eqauls 12 so you put a 12.0 and alighn the decimals like so 4.05

                         12.0 but you do this only if you are adding subtraction and multipling

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
