$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad

A=\pi (25x^4)\implies A=25\pi x^4$

Below are several points on the graph of a polynomial. Which of the following statements are true about the graph of this polyno

FinnZ [79.3K]

Notice that we need to look for the intervals of x and also for the intervals of y. We can observe that there is a minimum between x = 0 and x = 1 because the graph is descending and then ascending and also the graph has a maximum value between y = -3 and y = -1.
