What is the equation of the function shown in the table?

Input x -2 -1 0 1 2
Output y -3 -1 1 3 5
y = -x - 1
y = 2x + 1
y = 2x - 2
y = -2x + 1

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

can you put the picture up?

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
