a3. The shape will be shaped like a diagonal line decreasing as we go right.
a4. The shape will be shaped like a U facing upwards.
a5.The shape will be shaped like a U facing downwards.
a6. The shape will look like a S shape and it increases as we go right.
a7. The shape will look like a S shape and it decreases as We go right.
a8. The shape look like a W shape and it facing upwards.
a9. The shape look a W shape facing downwards.
We are given function.
b. We can test by the Rational Roots Test,
This means a the possible roots are
plus or minus(1,2,4,8).
c. If we apply Descrates Rule of Signs,
- There are 3 possible positive roots or 1 possible positive root.
- There are also 1 possible negative root.
- There is also 1 possible complex root.
d. Use Desmos to Graph the Function. Some roots are (-2,1,4).
e.
f. The complex zeroes are
i and -i
