Find the intervals on which f is increasing and decreasing.
f(x)=cos^2(x) on [-pi, pi]

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
