p(x) = 1/2 x - 3
1) Type of function: linear function
2) Doman: all real number
3) Range: all real number
4) x-intercept:
1/2 x - 3 = 0
1/2 x = 3
x = 3 * 2
x = 6
x-intercept: (6 , 0)
5) y-intercept: x = 0; y = -3
So y-intercept: (0, -3)
6) p(x) = 1/2 x - 3
x = 0; y = -3
x = 1, y = - 5/2
x = 2 , y = - 2
x = 4, y = -1
x = 6, y = 0
x = 8, y = 1 and so on....
The output values increase as the input values increase. so it's increasing.
