Question

Graph the function y=-x+3 using inputs of -1,0,1, and 2

Answer 1

Answer:

Given function:

$y=-x+3$

To graph the line using inputs -1,0,1 and 2.

Solution:

In order to find the points to be plot on graph we will plugin the input values as $x$ in the given function.

1) When $x=-1$

$y=-(-1)+3$

$y=1+3$

$y=4$

Point (-1,4)

2) When $x=0$

$y=-(0)+3$

$y=0+3$

$y=3$

Point (0,3)

3) When $x=1$

$y=-(1)+3$

$y=-1+3$

$y=2$

Point (1,2)

4) When $x=2$

$y=-(2)+3$

$y=-2+3$

$y=1$

Point (2,1)

The points to be plot in the graph are:

(-1,4),(0,3),(1,2),(2,1)
