Step-by-step explanation:

This is very simple.

f(x) means the function of x.

The question means,

"What is the function result if 2 was x"

The table does not show how it works, but it gives the result directly.

In the table, in the "x" column, there is a 2.

In the "f(x)" column, there is a 3 next to the number 2.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
