(3,4) in function notation

f(3) = 4 is the answer

The idea is that y = f(x) is the output while x is the input

A point like (3,4) has x = 3 and y = 4 pair up together

first one because it can't have a fraction in it

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
