How do I solve this ?
1 answer:
Answer:
See attachment :D
Step-by-step explanation:
y = 2/3x + 2
This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.
The line intersects with points (-3,0) and (0,2).
Hope this is helpful ^^ Good luck with your test :D

To find increasing and decreasing intervals we take derivative
Now we set the derivative =0 and solve for x
sinx + cosx =0
divide whole equation by cos x
tanx +1 =0
tanx = 1
and
Now we pick a number between 0 to
Lets pick
Plug it into the derivative
= 4.810 is positive
So the graph of f(x) is increasing on the interval [0, )
Now we pick a number between to 2pi
Lets pick
Plug it into the derivative
= 116 is positive
So the graph of f(x) is increasing on the interval
Increasing interval is
Decreasing interval is
(b)
The graph of f(x) increases and reaches a local maximum at
The graph of f(x) decreases and reaches a local minimum at
(c)
f(0) = 0
Here global maximum at
Here global minimum at
