Plug in the domain in the equation:
f(-3)=(-3)^2-3=6
f(0)=-3
f(1) = -2
f(2)=1
Range{6,-3,-3,1}

Answer:

see attached

Step-by-step explanation:

A graphing calculator does this very nicely.

The intercepts can be found by setting the other variable to zero and dividing by the coefficient of the variable of interest. This tells you the x-intercept is -2/3, and the y-intercept is -2/1 = -2. The y-intercept is conveniently on a grid point. To find other grid points on the line, it is convenient to choose integer values for x, then solve for y.

y = -3x -2

Positive values for y will require negative values of x.
