The value of the expressions are as follows:-

2 – 3f = -11.5

3f – 2 =  11.5

2f – 3 =   6

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The value of the functions by putting the value of f=4.5m will be:-

2   –   3f   =  2  -  (  3  x  4.5)  =   -11.5

3f  –   2    =  (  3   x   4.5 )  -  2 =  11.5

2f  –   3    =  (  2   x   4.5 )  -  3 =  6

Therefore the values are -11.5,11.5 and 6 for the given functions.
