Given:
The function are:


To find:
The function (f-g)(x).
Solution:
We have,


We need find (f-g)(x).



On combining like terms, we get


Therefore, the correct option is B.
Substitute -3 for x in the expression
f(x)= 53 - 2x
f(-3)= 53 - 2(-3)
multiply -2 * -3
f(-3)= 53 + 6
add
f(-3)= 59
ANSWER: f(-3)= 59
Hope this helps! :)
First you need to 48 into 28 and you add 28+26=54
then sub 54-2=52 then 52- -1=-51
so its -51
3x + 4 = 2x + 27
3x - 2x = 27 - 4
x = 23 <==
