Textbook Problem

The graph of a function g is shown below.
a. Is $g\left(0\right)$ positive or negative?
b Find an approximate value of x so that $g\left(x\right)=0$ .
c. Find approximate values for $x_1$ and $x_2$ so that $g\left(x_1\right)=g\left(x_2\right)=1$ but $x_1\ne x_2$ .
d. Find an approximate value for x such that $g\left(x\right)=-2$ .
e. As x increases from $-2$ to 1, do the values of g increase or decrease?
f. As x increases from 1 to 3, do the values of g increase or decrease?
