If f (x) is parallel to the line Y = 3/4*+2/5

which function could be f (x)

Any function that has the slope of 3/4

Reason: In order for the 2 functions to be parallel they must have an equal distance between them at all times (meaning if one function has a slighty different slope, than the two will intersect and will no longer be parallel). So the only way for the two lines to be parallel is if the two functions have the same slope
