To find f (3) on the graph below you would perform which of the following

What is f(3) for the quadratic function f(x)= 2x^2+ + x - 12

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

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)
