Question

If f(x) = 0.8(2 – x), what is the value of f(–2)?

Answer 1

3.2, I think

Answer 2

distribute -2 where 'x' variable are;
f(x) = 0.8(2 - (-2))
f(x) = 0.8(2 + 2)
f(x) = 0.8(4)
f(x) = 3.2

Answer 3

@Jadeishere is right
but in explanation time:
when you are replacing a variable in a fucntion, it changes all the variables into the desired number
so in this case you would replace x=-2
then you do your eqaution
now what if i say i want a sequence... well thats different
