Question

Graph by plotting points f(x)=3x+1;(-2,2)

Answer 1

The graph is shown below. The points for the graph are
`(-2,-5)` and
`(2,7)`.

Explanation:

Given:

The function is
`f(x)=3x+1`

Values of
`x` are -2 and 2.

Evaluate the value of the function at
`x=-2` and
`x=2`.

`f(x=-2)=3(-2)+1=-6+1=-5`

`f(x=2)=3(2)+1=6+1=7`

Therefore, the points on the graph are
`(-2,-5)` and
`(2,7)`.

Now, we plot the points on a graph and join the line passing through the two points.
