Answer:
- increasing on 0 < x < 2
- f(2) = 4
- decreasing on 2 < x < 5
Step-by-step explanation:
You need to know that an even function is symmetrical about the y-axis. The graph to the right of the y-axis is the mirror image of the graph to the left. With that in mind, the questions are easily answered.
It might help to draw the function graph, as we did in the attached. Then it is more straightforward to see what is happening in each of the intervals.
The function is increasing in the interval 0 < x < 2.
The function value at x=2 is 4: f(2) = 4.
The function is decreasing in the interval 2 < x < 5.
Answer:
Step-by-step explanation:
The equation of the line in point-slope form is:
Where m is the slope and is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:
