Answer:
The function f is graphed.
f is an even function as it has U- form.
As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).
The global minimum is (-9, -2) and the global maximum is infinity.
The minimum and maximums are the borders of the increasing or decreasing intervals.
<u>Intervals when the function is increasing: </u>
<u>Intervals when the function is decreasing: </u>
Answer:
y = -3x + 2
Step-by-step explanation:
To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2
