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.

Step-by-step explanation:
<u>X intercept is when y = 0. so...</u>
9x -15*0 = 45
9x = 45
x = 5. so the coordinate is (5,0)
<u>Y intercept is when x = 0. so...</u>
9*0 - 15y = 45
y = -3. so the coordinate is (0,-3)
then you plot these 2 points and draw a line going across them
Answer:
Step-by-step explanation:
By using linear regression calculator,
Linear regression equation representing the data set will be,
y = 7.79x + 34.27
Correlation coefficient of the line will be,
R = 0.98
Since, correlation coefficient of the line is (+0.98), relation between the two variables is a strong linear relationship.
That means hours spent studying has the strong relation with test scores obtained.
