Question
For each function, find (a) the critical numbers; (b) the open intervals where the function is increasing; and (c) the open intervals where it is decreasing.$$y=2.3+3.4 x-1.2 x^{2}$$
Step 1
The derivative of a function can tell us where the function is increasing or decreasing. The derivative of the function $y=2.3+3.4x-1.2x^{2}$ is given by: $$y'=3.4-2.4x$$ Show more…
