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

I'm presuming that you have a table like this, and that you want to find the values of f(x)?

 

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

 

 

So,    when  x = -2,    f(x) = 2 - 5(-2) = 2 + 5x2 = 2 + 10 = 12

         when  x = 1,   f(x) = 2 - 5(1) = 2 - 5x1 = 2 - 5 = -3

 

x	-2	-1	0	1	2
f(x)	12			-3

 

You then repeat this process for each of the values of x that you've been given (i.e. x=-1, x=0, x=2), putting the value of x into the equation for f(x) to find the answer.
