Question

What’s the function of f(x)= 4/5

Answer 1

Explanation:

remember the meaning of a function : it is the additional coordinate for the coordinate(s) used in the function expression :

f(x) = y = 4/5

that means for every possible value of x the corresponding y-value is 4/5.

this is a horizontal line going through 4/5 on the y-axis. that means through the point (0, 4/5).
