See below !

Explanation:

It's linear as you see the power of x first degree

GET

x-intercept when y=0

x=3

(3,0)

y-intercept when x=0

y=1

(0,1)

SO,

Take the two point and draw a straight line.

Please read the explanation.

Explanation:


Given:

Linear equation y=x3+1

Steps:

(1) Graph the Parent Function: y=x

(2) Graph the function y=x3

(3) Graph the given function y=x3+1

(4) Reflection

Step 1

Graph the Parent Function: y=x

enter image source here

Observe that the linear equation goes through the origin (0,0)

Step 2

Graph the function y=x3

enter image source here

Observe that the linear equation goes through the origin (0,0) as well similar to the parent function.

Step 3

Graph the given function y=x3+1

enter image source here

Observe the following:

(a) x-intercept is at (3,0)

(b) y-intercept is at (0,1)

Step 4

We will view all the graphs together and reflect on the behavior of the given function y=x3+1.

enter image source here

Reflection:

(a) Graph of the function y=x3 and the graph the given function y=x3+1 form parallel lines.

(b) Graph of the given function y=x3+1 is a vertical shift of 1 unit on the y-axis from the origin: (0,0).

Hope you find this solution helpful.
