The best way to approach a word problem like this
is to break it down into pieces, so we can understand it fully.
In this problem, we have a number, which we don't know.
We can use any variable to represent it.
So let's use the variable <em>n</em> to represent it.
"Two less than three times a number" means 3n - 2.
A common mistake is for students to put 2 - 3n.
However, the word "less than" switches the order around.
So we have 3n - 2 = 19.
Solving from here, we add 2 to both sides to get 3n = 21.
Now divide both sides of the equation by 3 and we have n = 7.
So the number is 7.

how to solve this problem the answer is -555498
Answer:
f(1) = -3
f(8) =3
f^-1 (5) =2
f^-1 (2) =4
Step-by-step explanation:
f(1) = is the value when x=1 which is -3
f(8) = is the value when x=8 which is 3
f^-1(5) is x value when y=5 so find y=5 in the table and read the x value x=2
f^-1 (2) is the x value when y=2 so find y=2 in the table and read the x value x=4
