Question

If f(x) = -2x + 1, find f(-6).

12

13

-11

-7

Answer 1

All what have you to do is to put -6 in place of x in the expression of f(x), can you have a try ?

Answer 2

if given f(x) = -2x + 1

f(0) = -2*0 +1
f(-1) = -2* -1 +1
f( 10) = -2*10 +1

hopefully you see the pattern with functions

Answer 3

f(-6)=-2(-6)+1
=12+1
=13
