Question

5 points) 1. Circle the correct answer. Use the graph of y = f(x) to solve f(x) < 0. A) (-2, 0) U (3,00) TVfx) B) (-2,0] [3,00) C) (-00, 2] U [0,3] D) (-00,-2) (0,3) E) none of the above

Answer 1

f(x)< 0 means al lvalue of x which makes graph of f(x) below x axis .

from given graph we have two region for f(x)<0

1) f(x) <0 for x from negative infinity upto -2 . so this is $\large (-\infty,-2)$

2) f(x) less than 0 between x=0 and 3 . so this region is (0,3) .

on compaining this two solution is

$\large (-\infty,-2)\cup(0,3)$
