- There are no critical points because the graph is neither continuous nor smooth. There is a discontinuity at x = 2.
- The absolute maximum is f(lim⇒-2_-) = infinity. The absolute minimum is f(lim⇒-2_+) = -infinity. This applies to the interval [-10, 7].
- The absolute maximum is f(5) = 26/7 or 3.714. The absolute mimimum is f(0) = 1.75. This applies to the interval [0, 5]. Proof: graph f(x) at [0, 5] on a graph or graphing calculator.For the function, f(x)=(9x+7)/(2x+4)
a. find the critical points or explain, with a derivative...

For the function, f(x)=(9x+7)/(2x+4)
a. find the critical points or explain, with a derivative, why there are no critical points.
b. find the x and y coordinates of the absolute maximum and absolute minimum of f(x) in the interval [-10, 7]. be sure to show all the necessary supporting calculus.
c. find the x and y coordinates of the absolute maximum and absolute minimum of f(x) in the interval [0, 5]. be sure to show all the necessary supporting calculus.
