Question

If f(x) = [[2x − 3]] − |3 − 2x|, what is the value of f(-2.8)?

Answer 1

So if we plug in 2.8 for every 'x' we see...we have

\[\large f(2.8) = [[2(2.8) - 3]] - |3 - 2(2.8)|\]
Lets simplify a little

\[\large f(2.8) = (5.6 - 3) - |3 - 5.6|\]

can you take it from there? :)

Answer 2

Oops, sorry...it was -2.8....

Answer 3

\[\large [[2(-2.8) - 3]] - |3 - 2(-2.8)|\]
\[\large (-5.6 - 3) - |3 + 5.6|\]

Nowww can you take it from there? :P

Answer 4

yes I can thank you so much hun
