the function f(x) is graphed below. what is true about the graph on the interval from point c to point d? answer it is positive and increasing it is positive and decreasing it is negative and increasing it is negative and decreasing
Answer
Explanation:
Step1: Check y - values
On the interval from c to d, the graph of the function (y = f(x)) lies below the x - axis. So, (f(x)<0) for (x\in(c,d)), which means the function is negative on this interval.
Step2: Check slope
As we move from left to right (from point c to point d) on the x - axis, the y - values of the function are getting larger. The slope of the tangent line to the curve is positive on this interval, so the function is increasing.
Answer:
It is negative and increasing
