Question

Model the function rule y = -2x - 3 with a table of values.show your work

Answer 1

To make a table with a function, you must have a set of inputs. In this case they'll be {2, 1, 0, -1, -2}

Then you plug in each input to find the output.

y=-2(2)-3
y=-4-3
y=-7

y=-2(1)-3
y=-2-3
y=-5

y=-2(0)-3
y=0-3
y=-3

y=-2(-1)-3
y=2-3
y=-1

y=-2(-2)-3
y=4-3
y=1

x: 2, 1, 0, -1, -2
y: -7, -5, -3, -1, 1
