Write a paragraph summarizing Gandhi’s influence. How should he be remembered?

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

Determine domain and range, largest open interval, and intervals which function is continuous.

Can someone me with this? i’m not sure what to put for my equations.
