F(x)
Can someone explain how to do F(x) problems

X | F(x)

-4 | -3

-2 | -1

0 | 1

2 | 3

4 | 5

Step-by-step explanation:

F(x) problems or function problems are input/output questions. You put the X value in for X in F(x) to get an output. In this question a graph is used. In this case the question gives a table, so you can simply find the inputs and outputs based on a pattern.

In the X-values or the input values: -4, -2, 0

You can keep going by two: 2, 4

In the F(x) values or output values: 1, 3, 5

You can't count backwards by two to get: -1, -3

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:
