QuestionUse the graph of $f$ to find $f(12)$ , $f(0)$ , and determine if $f(4)$ is positive or negative.

Studdy Solution

STEP 1

Assumptions1. The function $f$ is defined by the given graph. . The points on the graph are given as $(8,0), (4,-6), (0,-3), (-14,-6), (0,-3), (-,0), (-4,6), (-6,9), (-12,0)$ .
3. The function values for certain $x$ are given as $f(-14) = -6$ , $f(-4) =6$ , $f(12) =6$ , $f(0) = -3$ .
4. We are asked to find $f(12)$ , $f(0)$ , and whether $f(4)$ is positive or negative.

STEP 2

To find the value of $f(12)$ , we look at the given function values. $f(12) =6$

STEP 3

To find the value of $f(0)$ , we look at the given function values. $f(0) = -3$

STEP 4

To determine whether $f(4)$ is positive or negative, we look at the points on the graph. The point $(4,-6)$ is given, which means that $f(4) = -6$ .Since $-6$ is a negative number, $f(4)$ is negative.
