For y = x^2 + 10x + 24, write the axis of symmetry, the vertex, and whether the
parabola opens up or down.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Divide. write in the simplest form. 4 1/6 divided by 10

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)
