Hi I need help please this assignment is due today and I'm having trouble with it please help me

Question

In problems 1-4, the graph of a function is given. Use the graph to find:

(a) The intercepts, if any

(b) The domain and range

(c) The intervals on which it is increasing, decreasing, or constant

(d) Whether it is even, odd, or neither

1. The coordinates are (-4,2),(0,3),(-2,0),(2,0),(4,2)
2. The coordiantes are (-3,3),(-1,0),(0,2),(1,0),(3,3)
3. The coordiantes are (0,1)
4. The corrdinates are (1,0)

Answer 1

x-intercepts: when your points are (0, some #)

y-intercepts: when your points are (some #, 0)

Domain: all your x values

Range: all your y values

Intervals on whether increasing, decreasing or constant: once you have the points graphed you should be able to answer this. Interval (starting x value, ending x value)

Even functions: symmetric about the y-axis (imagine folding the graph vertically; does it match?)

Odd functions: symmetric about the y = x line (imagine folding the the graph twice; vertically then horizontally; does it match?)
