Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Which graph represents the function on the interval [−3, 3] ?

f(x) = [x] - 2

Answer 1

the answer is b! hope i could help!

Answer 2

Answer: (B) top right graph

Explanation:

First, determine what the coordinates are between x = -3 and x = 3. Remember, that a step function has a closed dot at the coordinate.

`\begin {array}c\underline{x}&\underline{\quad[x]-2\quad }&\underline{Coordinate}\\ -3&-3-2=-5&(-3,-5)\\-2&-2-2=-4&(-2,-4)\\-1&-1-2=-3&(-1,-3)\\0&\ 0-2=-2&(0,-2)\\1&\ 1-2=-1&(1,-1)\\2&\ 2-2=0&(2,0)\\3&\ 3-2=1&(3,1)\\\end{array}`

The only graph that satisfies these coordinates is the top-right graph.
