Answer:

(-1.7,1.7)

Step-by-step explanation:

OK, first draw the line y=4.

It's a bit misleading- where you think 4 should go is actually 2!

Check the scale and draw down where the two points meet on the line. They should be the same.

You get -1.7 and 1.7

The value of x is [tex]x=\pm\sqrt{3}[/tex]

Graph of parabola:

The given function is;

                        [tex]y=x^{2} +1[/tex]

We have to find value of x when [tex]y=4[/tex]

               [tex]y=x^{2} +1\\\\4=x^{2} +1\\\\x^{2} =4-1=3\\\\x=\pm\sqrt{3}[/tex]

Graph is also attached below.
