At x = -1 , 0 ,1 ,2 , the y value = 0, 1, 2, 3, Option C is the correct answer.
A function is a law that relates a dependent variable to an independent variable.
The points of line are
(- 1, 0), (0, 1),(1, 2).
The equation of the line formed will be
y = mx +c
[tex]\rm m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
m = 1
y = x +c
at x = 0 , y =1
c = 1
The equation is
y = x+1
The option 1 is
x = - 1, 0, 1, 2.
y1 = 0, 4, 6, 8.
y2= 0, 2, 4, 6
y3 =0, 1, 2, 3.
From the equation
at x = -1 , 0 ,1 ,2
the y value = 0, 1, 2, 3
Therefore Option C is the correct answer.
