Consider the given pre-image dilated by a scale factor
of 2, and answer the questions.
After applying the scale factor, what is the image?
What will be the new coordinate of the vertex at (3, 3) if
the vertex at (0, 0) remains the same?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
