Question

Use the function f(x)=2-5x to fill in the blanks in the table.

x f(x)
-2
-1
0
1
2

Answer 1

Answer: The required filled up blanks are

x -2 -1 0 1 2

f(x) 12 7 2 -3 -8

Step-by-step explanation: We are given to use the function f(x)=2-5x to fill up the following gaps :

x -2 -1 0 1 2

f(x) ? ? ? ? ?

We will be substituting the value of x in the expression for f(x) to find the required values.

We have

`f(-2)=2-5*(-2)=2+10=12,\\\\\\f(-1)=2-5*(-1)=2+5=7,\\\\\\f(0)=2-5*0=2,\\\\\\f(1)=2-5*1=-3,\\\\\\f(2)=2-5*2=-8.`

Thus, the required filled up blanks are

x -2 -1 0 1 2

f(x) 12 7 2 -3 -8
