Question

someone please show me how to do this

Answer 1

The 1 represents the y intercept so a point is (0,1). To find other points, plug in values for x. For example, plus in x and you get a y value of 2. So just plot a number of points and then connect them with a curved line( called a parabola).

Answer 2

for the equation y = x² + 1, we know the y-intercept is at (0,1) so we need to make a table and graph about 1
x   |   y
-5  |  26        Y = (-5)² + 1      Choose x values and find the y value after multiplying
-3  |  10                                  you can choose any x values you want, just make sure
 0  |    1                                  you have some negatives and some positives in your
 3  |  10                                  table.
 5  |  26

after you make a table with a few negative and positive points...graph
