Expert Solution
Step 1

THIS IS PROBLEM OF FINDING FUNCTION IN TERMS OF DIFFERENT GIVEN EXPRESSION OF ORIGINAL VARIABLE

HERE THAT VARIABLE IS 't' THE FUNCTION GIVEN IS x(t) WE HAVE GRAPH GIVEN OF THE FUNCTION FROM WHICH WE CAN FIND

THE VALUE OF FUNCTION AT ANY POINT LIKE WHEN 't' IS 0 => X(t) = 1, WHEN 't' IS -1 => X(t) = 0, WHEN 't' IS 2 => X(t) = 0,

FROM THIS VALUES WE CAN FIND ALL THE FUNCTIONS

FOR ANY FUNCTION WHICH IS SAID TO BE FUNCTION OF 't' CAN BE FORMULATED BY THIS THREE VALUES.

FOR EXAMPLE x(2t) WHERE INSTEAD OF 't' WE HAVE '2t'.

Step 2

given timetion xct) = 1 3 - T 2 3 XCE) = -I-t-o -0 jt te t=2 to find out x ( - +12) from act) you a-t|22 -4 -3 -2 -1 1 2 3 4
