To determine

(a)

Is $f\left(0\right)$ positive or negative?

To determine

(b)

For what values of $x$ does $f\left(x\right)=0$ ?

To determine

(c)

Find approximate values for $x_1\text{ and }{x}_2$ so that $f\left(x_1\right)=f\left(x_2\right)=1\text{ but }{x}_1\ne x_2$.

To determine

(d)

Find an approximate value for $x$ such that $f\left(x\right)=1.5$.

To determine

(e)

As $x$ increases from $-3\text{ to }-1$, do the values of $f$ increase or decrease?

To determine

(f)

As $x$ increases from $0\text{to}4$, do the values of $f$ increase or decrease?
